Abstract
An object of the present invention is to provide a solid electrolytic capacitor having reduced leakage current and a manufacturing method thereof. The solid electrolytic capacitor of the present invention includes a capacitor element including: an anodecomposed of a sintered body of metal particles; an anode leadprovided so that one end thereof is embedded in the anode; a dielectric layerformed on the surface of the anode; an electrolyte layerformed on the dielectric layer; and a cathode layerformed on the electrolyte layerso that an exposed faceof the electrolyte layerexists around the anode lead, wherein an anode terminalelectrically connected to the other end of the anode leadand a cathode terminalelectrically connected to the cathode layerare attached to the capacitor element, and a first resin partis provided to cover a part of the anode leadextending from the exposed faceof the electrolyte layerof the capacitor element to the anode terminal, and a second resin partis provided to cover at least the above capacitor element and the first resin part
