Abstract

According to the present disclosure, the breakage of an exterior body due to rising deformation of an electrode terminal can be prevented. The manufacturing method herein disclosed includes the steps of: bringing a lower surface of a terminal connecting part into contact with a first terminal, and bringing an upper surface of the terminal connecting part into contact with a second terminal; interposing the terminal connecting part, the first terminal, and the second terminal between a horn and an anvil, and carrying out ultrasonic welding; and accommodating the electrode body into the exterior body. Such a manufacturing method is characterized in that a width dimension of the horn is longer than a width dimension of the second terminal, and a width dimension of the anvil is longer than the width dimension of the second terminal. This can prevent rising deformation of the electrode terminal, and can prevent breakage of the exterior body by the deformed electrode terminal.
