Abstract
The purpose of the present invention is to provide an electricity storage device, the positive electrode and negative electrode of which can be protected when housing an electrode assembly body into a case main body. A secondary battery of the present invention has a lid terminal member formed by integrating: a lid; a positive electrode terminal and a negative electrode terminal; a positive electrode conductive member and a negative electrode conductive member; and an insulating member. The lid terminal member is integrated with an electrode assembly body through a positive electrode tab group and a negative electrode tab group. The electrode assembly body includes an electrode housing separator and a negative electrode each having a bottom-side contact portion contacting the inner bottom surface of a case main body. The electrode housing separator also has a lid-side contact portion contacting the lid terminal member.
