Title:
固体電解コンデンサおよびその製造方法
Document Type and Number:
Japanese Patent JP4439848
Kind Code:
B2
Abstract:
A capacitor element includes a valve metal foil including a core layer and a porous layer on the core layer, a dielectric layer on a portion of the valve metal foil excluding an end portion of the valve metal foil, a solid electrolyte layer on the dielectric layer, a collector layer on the solid electrolyte layer, and a zinc layer on the end portion of the valve metal foil. A solid electrolytic capacitor includes the capacitor element, an insulating case for sealing the capacitor element as to expose the zinc layer, a nickel layer on the zinc layer, and an electrode provided on the case and electrically connected to the collector layer. The solid electrolytic capacitor has a small impedance even at high frequencies, and has a small overall size and a large capacitance.
