`
`
`
`
`
`(57) Abstract: This secondary battery comprises: a battery case housing an electrode body; a sealing plate for sealing
`an opening of the battery case; current collector tabs provided respectively to a positive electrode plate and a negative
`electrode plate; current collector terminals provided onthe inside of the sealing plate and connected respectively to the
`positive electrode plate and the negative electrode plate through the current collector tabs; and external terminals provided
`on the outside of the sealing plate and connected to the current collector terminals. The electrode body is housed in the
`battery case, in a state where the current collector tabs are bent in a space on the inside of the sealing plate. The current
`collector tabs include: joint sections to which the current collector terminals are bonded by ultrasonic bonding; and bent
`sections whichare separated from the joint sections, are provided at positions on the electrode body side, and from which
`the bending of the current collector tabs starts.
