Abstract: This power storage module includes power storage devices (100), and a device holder (200) in which the power storage devices (100) are held. The device holder (200) includes accommodation parts (210) in which the power storage devices (100) are accommodated. Each accommodation part (210) includes a semicircular arc face (212) to which a peripheral face of the power storage device (100) is opposed, and linear faces (213) respectively continuous with both ends of the semicircular arc face (212) and each extending to an opening end of the accommodation part (210). Further, the power storage module includes an elastic adhesive (250) filled, in each accommodation part (210), between the peripheral face of the power storage device (100) and each linear face (213), and adhered to the peripheral face of the power storage device (100) and the linear face (213).

Abstract: A disclosed power storage device includes a power storage element, a case with a bottomed cylindrical shape having an opening at one end and housing the power storage element, and a sealing member for sealing the opening. The case has, in a vicinity of the opening, a first pressing portion pressing a side surface of the sealing member and protruding inward of the case, and a gas vent portion disposed nearer to the one end of the case than an apex which is the most protruded point of the first pressing portion. This can provide a power storage device including an explosion-proof mechanism that has high operational reliability and does not impair airtightness.
