<p>PROBLEM TO BE SOLVED: To provide a fixation structure capable of preventing processing of a member to be fixed, such as a terminal, from becoming complicated, and a method for manufacturing a battery.SOLUTION: The present invention comprises: a gasket 19 placed between a case lid part 4 and a terminal body part 11 inside a through-hole 10; an internal insulation plate 30 placed around an inner part 41 of the terminal body part 11 projecting onto an inner face 4b of the case lid part 4; and a washer 40 placed so as to sandwich the internal insulation plate 30 between the case lid part 4 and itself and having a hole 42 formed therein, through which the inner part 41 of the terminal body part 11 penetrates. At least part of the inner part 41 of the terminal body part 11 has an expanded-diameter part 50 formed therein whose diameter is expanded by plastic deformation, the expanded-diameter part 50 being fitted to an inner circumferential face of the hole 42 so as to restrict the terminal body part 11 from turning around the axis thereof.</p> |
