1. A power storage module, comprising:
a stack in which a plurality of power storage cells are stacked in a stacking direction;
a resin plate placed on the stack of the plurality of power storage cells;
a flexible printed circuit board placed on the resin plate and having an electric circuit electrically connected to the plurality of power storage cells; and
a cover member provided on the resin plate so as to cover the flexible printed circuit board, wherein
the resin plate includes a projection that extends through the flexible printed circuit board,
the cover member includes a tubular protrusion that protrudes toward the flexible printed circuit board on the resin plate,
the projection is accommodated in an inner periphery of the tubular protrusion, wherein an outer peripheral surface of the projection is spaced from an inner peripheral surface of the tubular protrusion, and
the tubular protrusion is in abutment with the flexible printed circuit board at a position to avoid the electric circuit.
