PROBLEM TO BE SOLVED: To provide a power storage device arranged so that a terminal can be cleaned readily while the worsening of sealability of a case, which is attributed to the terminal is suppressed.SOLUTION: A secondary battery 10 comprises: an electrode assembly 14; a case 11 in which the electrode assembly 14 is enclosed; and a positive electrode terminal 15 arranged to extend from inside the case 11 to the outside. The positive electrode terminal 15 has a positive electrode through-hole 70 arranged to pierce the case 11 from inside to outside. In such arrangement, the secondary battery 10 further comprises a seal member 80 for hermetically sealing an opening 72 located in the positive electrode through-hole 70 in the case 11; and the seal member is attached in the state of being in touch with the positive electrode terminal 15.SELECTED DRAWING: Figure 5 |
