Wiring module and electrical storage module

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.
