Document Type and Number:
WIPO Patent Application WO/2017/149949
Kind Code:
A1
Abstract:
A method for manufacturing an electrode body is provided with a step of performing ultrasonic welding of an exposed part, for which the surface of an electrode collector is exposed, with an electrode lead. The ultrasonic welding is performed in a state with the exposed part of the electrode collector and the electrode lead overlapping, and an ultrasonic horn pressed against the exposed part or the electrode lead with a resin sheet interposed therebetween. The resin sheet has a sheet base material, and an adhesive layer formed on one surface of the base material, and is adhered to the portion of the exposed part or the electrode lead that the ultrasonic horn contacts.
