Abstract

A power storage device (B) includes: a first power storage cell (10, 1(6)); a second power storage cell (10, 2(6)); and a wiring board (200). The wiring board includes a substrate (201, 201A to 201G), and a plurality of conductor members (211 to 216, 221 to 223, 231 to 236) provided on a vertically upper surface (F1) of the substrate. The plurality of conductor members include a first conductor member (211) and a second conductor member (212). The first power storage cell includes, on a vertically lower surface (F10) thereof, a first electrode terminal (11) connected to the first conductor member. The second power storage cell includes, on a vertically lower surface (F10) thereof, a second electrode terminal (12) connected to the second conductor member. At least one of a protrusion (M1, M21, M22), a recess (R10, R10A) and a through hole (h22, h22A, h22B) is provided in a portion of the substrate between the first electrode terminal and the second electrode terminal.
