    摘要: A secondary battery disclosed here includes; an electrode body; a battery case including a case body and a lid; an external terminal; and a gasket insulates the lid and the external terminal at an outer side of the battery case. The lid has an attachment hole to which the external terminal is attached. The external terminal includes a shaft inserted in the attachment hole and a head extending radially outward from one end of the shaft. The gasket includes a bearing portion disposed between a bottom surface of the head and the lid, and a side wall rising upward from the bearing portion. The head has a chamfered portion in which at least a part of an outer periphery of the bottom surface. A gap is formed between the chamfered portion and each of the bearing portion and the side wall.
