Japanese Patent JP6032060

B2

PROBLEM TO BE SOLVED: To provide a power storage device in which movement of an electrode assembly to an electrode side can be suppressed.SOLUTION: In a secondary battery 1, a bag-shaped insulating film 40 having a lower surface coating 41 covering a lower surface 23 and a side peripheral surface coating 42 covering a side peripheral surface 21 is fixed to an electrode assembly 20, and the insulating film 40 and a lower surface 11b of a case 10 are fixed by a fixing part 50 such as a double-side tape. More specifically, the electrode assembly 20 is fixed to the case 10 while interposing the insulating film 40. With such an arrangement, movement of the electrode assembly 20 to an electrode 30 side can be suppressed, even when the secondary battery 1 is turned up side down.
