Patent attributes
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 anode 3 composed of a sintered body of metal particles; an anode lead 2 provided so that one end thereof is embedded in the anode 3; a dielectric layer 4 formed on the surface of the anode 3; an electrolyte layer 5 formed on the dielectric layer 4; and a cathode layer 6 formed on the electrolyte layer 5 so that an exposed face 50 of the electrolyte layer 5 exists around the anode lead 2, wherein an anode terminal 1 electrically connected to the other end of the anode lead 2 and a cathode terminal 7 electrically connected to the cathode layer 6 are attached to the capacitor element, and a first resin part 10 is provided to cover a part of the anode lead 2 extending from the exposed face 50 of the electrolyte layer 5 of the capacitor element to the anode terminal 1, and a second resin part 8 is provided to cover at least the above capacitor element and the first resin part 10.
