Abstract
A method for producing an electrode assembly includes a step of ultrasonically welding an exposed portion where the surface of an electrode current collector is exposed and an electrode lead to each other. The ultrasonic welding is performed, while the exposed portion of the electrode current collector and the electrode lead are stacked on each other, with an ultrasonic horn pressed against a resin sheet disposed on the exposed portion or the electrode lead. The resin sheet includes a sheet base material and an adhesive layer formed on one surface of the base material and is bonded to a portion of the exposed portion that is to be in contact with the ultrasonic horn or to a portion of the electrode lead that is to be in contact with the ultrasonic horn.
