Method of manufacturing electrode

Abstract

A first aspect of the present disclosure relates to a method of manufacturing an electrode. The method includes a laminating step of laminating a thermoplastic resin material on a peripheral edge portion of a metal foil, a first welding step of irradiating a first region among a plurality of regions obtained by dividing a region on the resin material in a direction intersecting with a circumferential direction of the resin material with laser light to melt the resin material and welding the metal foil and the resin material to each other, and a second welding step of irradiating a second region different from the first region among the regions with the laser light after the first welding step to melt the resin material and welding the metal foil and the resin material to each other.

Dependencies are inferred from the claim text.
