PROBLEM TO BE SOLVED: To provide a battery module that can prevent wiring members arranged in a predetermined direction from short-circuiting each other and allows the wiring members to properly expand and contract in an array direction of battery cells.SOLUTION: A battery module 1 comprises: a plurality of wiring members 21 which have connection terminals at their tip connected to electrode terminals 2a, 2b of battery cells 2 and extend along an array direction D1 of battery cells 2; a plurality of resin parts 22 which are spaced as predetermined to cover the plurality of wiring members 21 arranged along a predetermined direction D2 crossing the array direction D1; an inter-resin-part extension/contraction part 23 which is connected to one resin part 22 and the other resin part 22 spaced as predetermined, and can extend and contract in the array direction; an in-wiring-member extension/contraction part 26 which is formed at a wiring member 21 and can extend and contract in the array direction D1 as a predetermined part deforms; and a position restriction part 24 which restricts a position of the in-wiring-member extension/contraction part 26 in the predetermined direction D2 while allowing the in-wiring-member extension/contraction part 26 to have the predetermined part deformed.SELECTED DRAWING: Figure 1 |
