<P>PROBLEM TO BE SOLVED: To provide a capacitor device which improves productivity while maintaining performance of a capacitor element housed therein. <P>SOLUTION: A capacitor device 100 includes: a case 10 in which a flange 32 is formed on a periphery of an opening end part; a capacitor element 12 housed in the case 10 and electrically connecting with the exterior of the case 10; and a cover 14 which contacts with the flange 32 and covers an opening of the case 10. Laser joining parts 18 are formed on at least a part of a contact portion between the flange 32 and the cover 14, and a cut-out part 16 is formed at an outer peripheral part of an upper surface 142 of the cover 14, the outer peripheral part corresponding to the laser joining parts 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
