<p>PROBLEM TO BE SOLVED: To suppress generation of defects caused by expansion of a power storage element.SOLUTION: A power supply module 1 comprises: a plurality of arranged nonaqueous electrolyte secondary batteries 10; and a cushioning implement 40 located at a gap between adjacent nonaqueous electrolyte secondary batteries 10. The cushioning implement 40 has: a contact surface 43a contacted with an intermediate part of a wide surface 11a of one of adjacent nonaqueous electrolyte secondary batteries 10; and contact surfaces 41a and 42a contacted with both end sides of a wide surface 11a of the another of the adjacent nonaqueous electrolyte secondary batteries 10. The contact surface 43a and the contact surfaces 41a and 42a are arranged separately when viewed from the arrangement direction of the adjacent nonaqueous electrolyte secondary batteries 10.</p> |
