SOLID ELECTROLYTIC CAPACITOR |
摘要 |
PROBLEM TO BE SOLVED: To reduce a leakage current while miniaturizing a solid electrolytic capacitor. SOLUTION: The solid electrolytic capacitor comprises: an anode body 1; a dielectric film 2 provided on the surface of the anode body 1; a solid electrolyte 3 provided on the surface of the dielectric film 2; and a capacitor element 5 made of a collector 4 provided on the surface of the solid electrolyte 3. The anode body 1 is formed by winding a valve metal wire, prevents a metal base on an electrode end face from being exposed by a slitter, dispenses with the formation of the dielectric film on an exposed metal element by aging as before, and achieves an operation effect for suppressing an increase in a leakage current caused by the dielectric film.
