The present invention has a small size, high capacity, low ESR, and excellent LC value, and is obtained by sequentially laminating a dielectric oxide film layer, a semiconductor layer, and a conductor layer on the surface of a valve action metal sintered body or a conductive oxide sintered body to which an anode lead is connected. A solid electrolytic capacitor comprising a capacitor element, the present invention relates to a solid electrolytic capacitor having a thickness of 5 μm or less in the vicinity of an anode lead connection point of a sintered body surface to which an anode lead is connected, and also to an electronic circuit and an electronic device using the capacitor. will be. |
