<p><P>PROBLEM TO BE SOLVED: To provide an electrolytic capacitor which improves vibration resistance and insulation quality by using a simple manufacturing method, and to provide a method for manufacturing the electrolytic capacitor. <P>SOLUTION: An electrolytic capacitor 1 includes a capacitor element 10 formed by overlapping a valve metal anode foil 2 on a valve metal cathode foil 3 with a sheet of electrolytic paper (separator) 4 sandwiched therebetween and rolling up the overlapped anode foil 2 and cathode foil 3, a cup shaped exterior case 5 in which the capacitor element 10 is inserted from a roll end surface 10a to be housed, and an elastic sealing member 7 sealing an opening of the exterior case 5. The electrolytic capacitor 1 further includes an insulation sheet 20 or insulation bags 40 and 41, which cover at least part of an outer peripheral part 10b and the roll end surface 10a, between the capacitor element 10 and the exterior case 5. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
