Abstract

A battery pack (1) includes: a battery module (20) including cells (21) and intervening members (31); a cooler (60); and a heat conductive layer (70) provided between heat dissipation surface (23b) of the cell (21) and a cooling surface (60a) of the cooler (60). The intervening member (31) includes a second intervening portion (35) to be provided between the heat dissipation surface (23b) and the cooling surface (60a). The second intervening portion (35) has a thickness (T2) and includes a communicating-passage side wall portion (35f) having a tapered shape directed outward along a direction from the heat dissipation surface (23b) toward the cooling surface (60a). The heat conductive layer (70) has a layer thickness (TD) that is equal to or more than the thickness (T2) of the second intervening portion (35) and is filled in at least the communicating passage (35k).
