Abstract
A battery module includes: a plurality of battery cells each of which has a flat shape; a plurality of elastic spacers laminated and disposed alternately with the battery cells; and a restraining member configured to restrain the battery cells and the elastic spacers in a laminating direction of the battery cells. Each of the elastic spacers has a sheet portion that extends between two adjacent battery cells and a plurality of protrusions that protrudes from one surface of the sheet portion. The protrusions are disposed at an equal interval along at least a first direction. When an interval between the protrusions in the first direction is x and a dimension of each protrusion in the first direction is y, relationships of 4 mm≤y≤18 mm, y≥4/9x−10/3, and y≤x−2 are satisfied.
