1. A method for manufacturing a battery module, the method comprising:
an inserting step of inserting a battery cell in a battery retaining section of a holder having the aperture-shaped battery retaining section, and provides an adhesive between an inner circumferential surface of the battery retaining section of the holder and an outer circumferential surface of the battery cell; and a cell fixing step of fixing the inner circumferential surface of the battery retaining section and the outer circumferential surface of the battery cell by the adhesive, wherein in the inserting step, an adhesive layer that is formed of the adhesive and provided between the inner circumferential surface of the battery retaining section and the outer circumferential surface of the battery cell on an entire circumference of the battery cell in a circumferential direction at least in a part of a region of the battery cell in an axial direction is formed, wherein the adhesive layer has a layer structure including a holder-side adhesive layer that makes contact with the inner circumferential surface of the battery retaining section and a cell-side adhesive layer that makes contact with the outer circumferential surface of the battery cell, and wherein different types of adhesives are used as the adhesive configuring the holder-side adhesive layer and the adhesive configuring the cell-side adhesive layer. |
