| abstract |
The present invention relates to an electric double-layer device provided with a urethane potting part (50) which fills each of a gap between a first terminal (21) and a first through-hole (41) and a gap between a second terminal (22) and a second through-hole (42), the first terminal (21) and the second terminal (22) being exposed to the outside of a rubber closure (40), and aluminum terminals (A) of the first terminal (21) and the second terminal (22) are anodized, thereby enabling the formation of aluminum oxide films (A1), thereby enabling a relative increase in lifespan. |
