The invention relates to a buttery unit (1) that includes a case (20) accommodating an electrode assembly (10), the case (20) having an opening (21) and a cap plate (310) for closing the opening (21), the cap plate (310) having a terminal insertion portion (35, 36). The battery unit (1) further induces a terminal member (320, 330) extending into the case (20) through the terminal insertion portion (35, 36) from outside the case (20) and being coupled to the electrode assembly (10), the terminal member (320, 330) including a current collector (324, 334) electrically and mechanically coupled to the electrode assembly (10); a terminal portion (321, 331) extending parallel to an outer surface (312) of the cap plate (310) at an outside of the cap plate (310); and a connection portion (325, 335) electrically coupled to the current collector (324, 325) and to the terminal portion (321, 331). In order to provide a large contact surface and to avoid unintended electrical contact between the terminal portion (321, 331) and the cap plate (310), a gap (G1, G2) separates the terminal portion (321, 331) and the cap plate (310). |
