Abstract
A method for producing a power storage device includes an insert-molding step of making a resin member by insert-molding with respect to a terminal member inserted in an insertion hole of a lid. In this insert-molding step, the insertion hole of the lid is placed in front of a gate, and a molten resin is injected through the gate to flow in an opposite gate-side space in a cavity through the insertion hole, allowing the molten resin to spread over the entire cavity, to form the resin member.
