Japanese Patent JP6979372

B2

An object of the present invention is to provide a secondary battery module having superior ease of assembly and which enables secondary batteries to be arranged in fixed positions even when the size of a secondary battery laminate in a laminating direction changes before and after compression. This secondary battery module comprises a secondary battery having a wide surface and a narrow surface and a terminal provided protruding from the narrow surface, a secondary battery laminate in which a plurality of the secondary batteries are laminated so that the wide surfaces are caused to face each other and the terminals are oriented toward one side, and a busbar case provided so as to face a side on which the terminals of the secondary battery laminate are provided, wherein the busbar case has a plurality of holes at positions respectively corresponding to the terminals, the terminals are inserted into the holes, and a length M of a sum in the laminating direction of a gap E, which is a gap on an outside in the laminating direction among gaps between the secondary batteries and inner walls of the holes and which are provided on one end of the secondary batteries in the laminating direction, and a gap F, which is a gap on an outside in the laminating direction among gaps between the secondary batteries and inner walls of the holes which are provided on another end of the secondary batteries in the laminating direction, satisfies Formula (1) below.
