`AMENDMENTS TO THE CLAIMS
`
`This listing of claims replaces all prior versions of claims in the application.
`
`Listing of Claims:
`
`1. (Currently Amended)
`
`A posittve-electredefera secondary battery, comprising:
`
`a positive electrode comprising:
`
`a positive electrode current collector;
`
`an intermediate layer disposed on the positive electrode current collector; and
`
`a positive electrode mixture layer disposed on the intermediate layer and including
`
`a positive electrode active material,
`
`wherein the intermediate layer includes: a conductive agent, a metal phosphorus
`
`oxide, and an inorganic compoundother than the metal phosphorus oxide, the inorganic
`
`compound having a lower oxidative power than that of the positive electrode active
`
`material;
`
`a negative electrode;
`
`a separator disposed betweenthe positive electrode mixture layer of the positive electrode
`
`and the negative electrode: and
`
`an electrolyte,
`
`wherein the metal phosphorus oxide and the inorganic compoundare present in a part of
`
`the positive electrode mixture layer extending from the interface between the positive electrode
`
`mixture layer and the intermediate layer to a level of about 1/5 of the thickness of the positive
`
`electrode mixture layer.

`3. (Currently Amended) The pesitive-eleetredefora secondary battery according to claim 1,
`
`wherein a content of the metal phosphorus oxide is 80 mass% or more and 99.5 mass% or less
`
`based on the total amount of the metal phosphorus oxide and the inorganic compound.
`
`4. (Currently Amended) The pesittve-eleetredetera secondary battery according to claim 3,
`
`wherein the metal phosphorus oxide has a Mohs hardnessof7 orless.
`
`5. (Currently Amended) The pesittve-cleetredefora secondary battery according to claim 1,
`
`wherein a ratio between an averageparticle diameter of the metal phosphorus oxide and an average
`
`particle diameter of the inorganic compoundis 0.5:1 to 2:1.
`
`6. (Currently Amended) The pesttive-electredefor-a secondary battery according to claim 1,
`
`wherein an averageparticle diameter of the metal phosphorus oxide is 0.05 um or more and 5 um
`
`or less, and an average particle diameter of the inorganic compound is 0.1 um or more and 5 um
`
`or less.
`
`7. (Currently Amended) The pesttive-electredefora secondary battery according to claim 1,
`
`wherein the metal phosphorusoxide includes at least one of the group consisting of LisPO4, LiPON,
`
`LixHPOs, LiH2POs, Na3sPO4, NaxHPOs, NaH2POs, Zr3(PO4)4, Zr(CHPO4)2, HZr2(PO4)3, K3POs,

`
`AgI-Ag20-P20s.
`
`8. (Currently Amended) The pesittve-cleetredefora secondary battery according to claim 1,
`
`wherein the inorganic compoundincludesat least one of the group consisting of aluminum oxide,
`
`titanium dioxide, silicon dioxide, and manganeseoxide.
`
`9. (Canceled)
`
`10. (Currently Amended) The secondary battery according to claim 1 [[9]], wherein in a part of
`
`the positive electrode active material layer extending from the surface on the separator side to a
`
`level of about 4/5 of the thickness of the positive electrode active material layer in the thickness
`
`direction of the positive electrode active material layer, the total amount of the metal phosphorus
`
`oxide and the inorganic compoundother than the metal phosphorus oxide included therein is less
`
`than 0.5 mass%.
