Abstract: A pressurizing structure for a storage battery applies pressure in a thickness direction to a structure including a storage battery cell with an electrode portion packaged with a laminate exterior material or including a laminate in which a plurality of storage battery cells are laminated. The pressurizing structure includes a pair of end plates disposed at corresponding ends of the structure in the thickness direction, and a fastening member configured to fasten the pair of end plates to each other. An elastic body is disposed at at least one position sandwiched between the end plate and the structure. A rigid body is disposed at a position sandwiched between the elastic body and the structure, and any one of the end plate, the elastic body, and the rigid body further includes a deformation preventing portion configured to prevent deformation of the elastic body in a direction perpendicular to the thickness direction.
