Abstract

Provided is a power storage module that can easily and reliably link a plurality of power storage modules.　The present invention provides a power storage module comprising a housing 1 and a unit cell group accommodated in the housing 1. A male terminal 3a and a female terminal 3b, corresponding to electrodes of the unit cell group, are provided inside the housing 1, and a male-side opening 16a and a female-side opening 16b, corresponding to the male terminal 3a and the female terminal 3b, are formed in the housing 1. The male terminal 3a comprises: a mating protrusion 32a projecting outward through the male-side opening 16a; a male-side contact provided on the mating protrusion 32a; and a male-side conduction means electrically connecting the male-side contact to an electrode of a unit cell group. The female terminal 3b comprises: a mating recess 32b disposed opposing the female-side opening 16b; a female-side contact provided in the mating recess; and a female-side conduction means electrically connecting the female-side contact to an electrode of the unit cell group. The mating protrusion 32b of the male terminal 3a can fit into the mating recess 32b of a female terminal 3b of another power storage module.
