Abstract
In a battery module in which battery cells are inserted and adhered to battery retention sections each having a hole and formed on a holder, an objective is to provide a technology for sufficiently filling the gap between the battery retention section of the holder and the battery cell with an adhesive. A deformable porous layer 40 is formed on an outer circumferential surface 11 of each battery cell 1, and an adhesion layer 4 is formed by impregnating the porous layer 40 with an adhesive. Alternatively, the deformable porous layer 40 is formed on the outer circumferential surface 11 of each of the battery cells 1, and an adhesive layer 46 including an adhesive is formed on the back side in an insertion direction with respect to the porous layer 40.
