PROBLEM TO BE SOLVED: To provide a technique for sufficiently filling an adhesive between a battery holding part of a holder and a battery cell, in a battery module formed with the battery cell inserted into and bonded to the hole-shaped battery holding part provided on the holder.SOLUTION: An adhesive layer for bonding together a holder 5 and a battery cell 1 in a battery module is configured to have a two-layered structure made up of a holder-side adhesive layer coming into contact with an inner peripheral surface 51 of a battery holding part 50 and a cell-side adhesive layer coming into contact with an outer peripheral surface 11 of the battery cell 1. Different types of adhesives are used as an adhesive for forming the holder-side adhesive layer and that for forming the cell-side adhesive layer 41. |
