<P>PROBLEM TO BE SOLVED: To provide a capacitor in which, even if a case is expanded by inner pressure rise, adhesion of a caulking part is not lost, and a manufacturing method of the capacitor. <P>SOLUTION: An opening 1a of a metal case 1 is sealed by a sealing body 2 in which a rubber body 2a is laminated on a surface of a hard substrate 2b at a side of the opening 1a, and a side surface of the metal case 1 is caulked with the side of the opening 1a as a deformation range while defining a corner part of the hard substrate 2b as a base point. A drawing part 6 is formed by caulking. Furthermore, since caulking is performed with an upper corner part of the hard substrate 2b as a base point, a part of the metal case 1 is drawn and deformed and at a capacitor element center side of the drawing part 6, a thin part 7 is formed which is thinner than the metal case 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
