PROBLEM TO BE SOLVED: To inhibit foreign materials from entering an electrode assembly.SOLUTION: When a power storage device includes an insulation cover 100 electrically insulating between a case 11 and a joint section formed between a positive electrode tab 31 projecting from an electrode assembly 14 and a positive electrode conductive member 40, and between the case 11 and a joint section formed between a negative electrode tab 32 projecting from the electrode assembly 14 and a negative electrode conductive member 60, holding tapes t1, t2 are adhered to a portion which does not overlap a cover facing region facing the insulation cover 100, on a tab side end surface 14c. Thus, by the insulation cover 100 and the holding tapes t1, t2, the tab side end surface 14c has less exposed portion.SELECTED DRAWING: Figure 4 |
