The invention relates to a battery unit (1) that includes a case (20) accommodating an electrode assembly (10) and having an opening (21), and a cap plate (310) closing the opening (21), and having a terminal insertion portion (35, 36). The battery unit (1) further includes a terminal member (320, 330) inserted into the case (20) through the terminal insertion portion (35, 36) from an exterior of the case (20) and coupled to the electrode assembly (10), the terminal member (320, 330) having a terminal portion (321, 331), extending in a major side direction of the cap plate (310) at an exterior of the cap plate (310), and being separated from an outer surface (312) of the cap plate (310). In order to increase mechanical stability, the battery unit (1) according to the invention further includes a support member (360, 370) coupled to the cap plate (310) and supporting the terminal portion (321, 331) with respect to the cap plate (310). |
