<P>PROBLEM TO BE SOLVED: To provide an electrolytic capacitor capable of suppressing a whisker from occurring and growing in a lead terminal for capacitors in which a metal plating mainly composed of tin is formed in an aluminium wire connected to a capacitor element. <P>SOLUTION: An electrolytic capacitor includes an aluminum wire 4 connected to an anode foil and a cathode foil, a connection part 5 formed at an end of the aluminum wire 4, and an extraction lead terminal 3 composed of a lead wire 6 bonded to the connection part 5. This aluminum electrolytic capacitor forms a cured resin layer 7 by filling the connection part 5 of the extraction lead terminal 3 with a liquid curable resin containing a scale-like filler, thereby suppressing a whisker from occurring and growing in the extraction lead terminal which does not use lead. <P>COPYRIGHT: (C)2012,JPO&INPIT |
