POWER STORAGE DEVICE
A power storage device includes a case member, a terminal member inserted in an insertion hole of the case member, and a resin member joined to the case member and the terminal member. The resin member includes, on a resin outer surface exposed on an outer side of the case member, at least any one of a recess and a projection portion increasing a creepage distance from a terminal outer surface, which is exposed on the outer side of the case member, of the terminal member to a case outer surface exposed on the outer side of the case member.
1 . A power storage device comprising:
a case member including an insertion hole;
a terminal member inserted in the insertion hole of the case member; and
a resin member joined to the case member and the terminal member while insulating between the case member and the terminal member, to fix the terminal member to the case member, wherein
the resin member includes, on a resin outer surface exposed on an outer side of the case member, at least any one of a recess and a projection portion increasing a creepage distance from a terminal outer surface, exposed on the outer side of the case member, of the terminal member to a case outer surface exposed on the outer side of the case member.
2 . The power storage device according to claim 1 , wherein
the terminal member includes a terminal outer portion located on the outer side of the case member, the terminal outer portion including a terminal top surface of a flat shape forming the terminal outer surface,
the resin member includes a resin outer frame portion located on the outer side of the case member, having a frame shape that surrounds a periphery of the terminal outer portion of the terminal member, and including a frame top surface flush with the terminal top surface of the terminal outer portion, and
the resin member includes, on the frame top surface of the resin outer surface, the recess of an annular shape surrounding a periphery of the terminal top surface.
