1. A power storage cell comprising:
a housing including a bottom surface and a side surface and defining an inner space;
an electrode body accommodated in the inner space of the housing; and
a gas discharge valve provided on the side surface of the housing, wherein the bottom surface of the housing has a first width along a first direction and a second width along a second direction, the second width being smaller than the first width,
the side surface of the housing includes a first side surface and a second side surface that are respectively located at ends of the housing in the first direction,
the electrode body is accommodated in the inner space to form an upper clearance on a side opposite to the bottom surface and form a side clearance between the electrode body and each of the first side surface and the second side surface,
the gas discharge valve includes a first discharge valve provided on the first side surface and a second discharge valve provided on the second side surface,
an entire opening of the first discharge valve is located at a region of the first side surface to which the upper clearance is projected, and the entire opening of the first discharge valve overlaps the upper clearance when viewed along the first direction,
an entire opening of the second discharge valve is located at a region of the second side surface to which the upper clearance is projected, and the entire opening of the second discharge valve overlaps the upper clearance when viewed along the first direction, and
the openings of the first discharge valve and the second discharge valve do not overlap the electric body when viewed along the first direction so that both the first discharge valve and the second discharge valve maintain the function of discharging gas.
