PROBLEM TO BE SOLVED: To provide a battery pack in which the cooling performance of a battery can be ensured by reducing a thermal resistance existing between a battery cell and a cooler, and manufacturing method therefor.SOLUTION: A battery pack 1 includes a plurality of battery cells 3, a cooler 5 constituted to have a cooling plate 50 provided to conduct heat to a body in contact with a heating medium, and an intermediate member 4 having thermal conductivity and interposed between the battery cells 3. The intermediate member 4 is a member having a main wall 40 held by adjacent battery cells 3 from both sides, a fitting piece 42 to be fitted in a through hole 51 formed in the cooling plate 50, and a sidewall 41 having a shape extending from one end of the main wall 40 in the thickness direction X and coming into contact with the cooling plate 50. |
