PROBLEM TO BE SOLVED: To provide a vibration resistance performance of a collector supporting a power storage element.SOLUTION: In a power storage device, an electrode terminal TM is disposed outside of a device casing BC, and a power storage element 3 and collectors 4 and 6 constituting an electrification path between the power storage element and the electrode terminal are disposed inside of the device casing BC. The collectors 4 and 6 are formed from plate materials, support the power storage element 3 at positions connected with the power storage element 3, and are fixed to an inner wall surface of the device casing BC in mounting parts of which the attitudes become approximately parallel with the inner wall surface of the device casing BC while being positioned at a side of a connection position to the electrode terminal TM. Wall bodies 4b and 6b are formed in the mounting parts of the collectors 4 and 6 and positions to form the wall bodies 4b and 6b are set within a range including at least a fixture position to the device casing BC in a direction view of moment of a force acting on fixture positions of the collectors 4 and 6 with the power storage element 3. |
