Abstract

A battery module is configured so that cooling performance can be improved. The battery module includes multiple battery cells stacked on each other, a spacer provided at an end portion of each battery cell, and heat transfer plates each of which has a heat absorption portion arranged between the multiple battery cells stacked on each other to absorb heat from the battery cells and a heat dissipation portion dissipating the heat absorbed by the heat absorption portion to the outside. The heat dissipation portion is bent relative to the heat absorption portion 20a, and is exposed through between the battery cells to contact the spacer. The spacer includes contact portions having contact surfaces contacting the heat dissipation portion, and a positioning portion having a surface facing a direction opposite to that of the contact surface and defining the position of the spacer.
