Abstract
An energy storage apparatus includes an outer case which includes a body portion which accommodates an energy storage device and a lid body which closes an opening portion of the body portion in a state of being integrally joined to the opening portion, and a restricting member. The restricting member includes an abutment portion which abuts on an upper surface of the lid body, which is a surface on a side opposite to the body portion, to restrict movement of the lid body in a direction away from the opening portion, and a fixing portion fixed to the body portion.
