Abstract

The present disclosure provides a manufacturing method for an electrical energy storage device including an electrode body, a case, and a first electrode terminal attached to a bottom wall of the case. This manufacturing method includes a step of electrically connecting a first current collecting member to the electrode body, a step of inserting the electrode body into the case main body and disposing at least a part of the first current collecting member into a first concave part of the first electrode terminal, and a step of delivering an energy beam from a side of the first electrode terminal, thereby joining by welding the part of the first current collecting member that is disposed inside the first concave part to the first electrode terminal.
