The second holding portion is contiguous with the first holding portion. The first and second holding portions include separating walls that face side edges of the connection members, and coupling portions that couple the first and the second holding portions to each other. The separating walls include enlarged gap portions that are formed so that gaps between the enlarged gap portions and the side edges of the connection members are larger on the side where the coupling portions are located than on the side where ends of the connection members are located. ## Claims ### Claim 1 A wiring module comprising: a connection member for connecting electrode terminals of a plurality of electrical storage elements, each electrical storage element including a positive electrode terminal and a negative electrode terminal; and an insulating protector in which the connection member is accommodated, wherein the insulating protector is provided with a first unit that includes a first holding portion that holds one end side, in a connection direction, of the connection member, and a second unit that includes a second holding portion that holds the other end side, in the connection direction, of the connection member, the second holding portion being contiguous with the first holding portion, the first holding portion and the second holding portion include separating walls that face side edges of the connection member extending in the connection direction, and coupling portions that couple the first holding portion and the second holding portion to each other, and the separating walls each include an enlarged gap portion that is formed such that a gap between the enlarged gap portion and the side edge of the connection member that extends in the connection direction is larger on the coupling portion side than on a side where an end, in the connection direction, of the connection member is located. ### Claim 2 (depends on 1) The wiring module according to claim 1, wherein the connection member is provided with through holes through which fastening members for fastening the connection member to the electrical storage elements are inserted, and the enlarged gap portions are formed on the coupling portion side in the connection direction of the connection member with respect to centers of the through holes. ### Claim 3 (depends on 1) The wiring module according to claim 1, wherein at least one of the first holding portion and the second holding portion, and the connection member are capable of slidingly moving in the connection direction of the connection member, and the side edges, in the connection direction, of the connection member are respectively provided with engaged portions, and the at least one of the first holding portion and the second holding portion is provided with engaging portions that engage with the engaged portions to allow the sliding movement over a range of a predetermined clearance. ### Claim 4 (depends on 3) The wiring module according to claim 3, wherein the enlarged gap portions are formed on the coupling portion side with respect to the engaging portions. ### Claim 5 (depends on 1) The wiring module according to claim 1, wherein the enlarged gap portions are formed so that the gap between the separating walls and the side edges of the connection member that extend in the connection direction increases toward the coupling portion side. ### Claim 6 (depends on 1) An electrical storage module comprising: a pair of electrical storage element groups in each of which the plurality of electrical storage elements are stacked, and the wiring module according to claim 1, wherein the first unit is mounted on one of the pair of electrical storage element groups, and the second unit is mounted on the other one of the electrical storage element groups.
