Wiring module and power storage module

A wiring module capable of attachment to a power storage element group in which a plurality of power storage elements are arranged side-by-side, each of the power storage elements having an electrode face on which positive and negative electrode terminals are provided, the wiring module comprising:

• a plurality of bus bars that electrically connect the electrode terminals to each other;
• a resin protector that has one or a plurality of holding portions that hold the plurality of bus bars, and is provided with a tolerance absorbing portion that absorbs tolerance in an arrangement direction of the power storage elements;
• and
• a cover that is attached to the resin protector and covers all of the holding portions,
• wherein the resin protector is provided with a locking portion that locks the cover, the locking portion projecting in a direction identical to a projecting direction of the electrode terminals and extending along the arrangement direction,
• the cover is provided with a lock-receiving portion that is locked to the locking portion, and
• the locking portion and the lock-receiving portion are locked in a manner of enabling relative movement along the arrangement direction at an edge portion of the cover that extends in the arrangement direction, wherein the tolerance absorbing portion of the resin protector absorbs tolerance such that the locking portion is configured to slide along the lock-receiving portion while remaining engaged with the lock-receiving portion in response to movement of the power storage elements relative to the cover along the arrangement direction of the power storage elements.
