Power storage module

A power storage module comprising:

• a stack in which a plurality of power storage cells each including an electrode terminal and a gas discharge valve are stacked in a stacking direction;
• a resin plate having a bottom surface portion extending in each of the stacking direction and a width direction orthogonal to the stacking direction, the resin plate being placed on the stack;
• a flexible printed circuit board placed on the bottom surface portion and having an electric circuit electrically connected to the plurality of power storage cells;
• and
• a connection terminal provided on the flexible printed circuit board and electrically connected to the electrode terminal, wherein
• the resin plate is provided with
• a gas exhaust port formed in the bottom surface portion at a position facing the gas discharge valve,
• an opening formed in the bottom surface portion at a position facing the electrode terminal, and
• a wall portion that protrudes from the bottom surface portion at positions on outer sides with respect to the gas exhaust port in the width direction and that discontinuously extends in the stacking direction,
• the connection terminal is electrically connected to the electrode terminal while penetrating the opening,
• the flexible printed circuit board has a main body portion, and a connection piece portion that extends from the main body portion and is curved so as to be connected to the connection terminal,
• a first gap is formed between the main body portion and the connection piece portion, and
• a first auxiliary wall portion is provided in the first gap, the first auxiliary wall portion protruding from the bottom surface portion and extending in the stacking direction.
