Abstract: At least one cylindrical electricity storage device, and an upper holder for holding an upper end side of the electricity storage device are included. A positive electrode terminal and a negative electrode terminal are disposed on an upper end part of the electricity storage device, and the negative electrode terminal is positioned in the outer side than the positive electrode terminal in a radial direction of the electricity storage device. A negative electrode lead connected to the negative electrode terminal from the outer side in the radial direction is further included. The upper holder includes a restriction part positioned in the inner side than at least a part of the negative electrode lead. A bottom surface of the restriction part protrudes toward the lower part than the surface facing an end part of one side of the electricity storage device in the upper holder.
