<P>PROBLEM TO BE SOLVED: To provide an electrolytic capacitor and method for manufacturing the same, capable of the operability of a safety valve that is burst at a fixed internal pressure lower than a sealing force by a sealing member when an internal pressure of an outer case formed from aluminum rises because organic solvent constituting electrolyte impregnated into a capacitor element vaporizes by an internal temperature rise and the electrolytic capacitor with the flat outer case generates hydrogen gas by an electrochemical reaction. <P>SOLUTION: The electrolytic capacitor is of a bottomed cylindrical type and includes an outer case formed from an opposing plane section of the cylindrical body and a curved section that continuously opposes to the plane section and is narrower than the plane section. The electrolytic capacitor further includes a safety valve on at least one curved section in the longitudinal direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
