Abstract:
1. A solid electrolytic capacitor comprising: a capacitor element including another capacitor element stacked on the capacitor element, the another capacitor element including another anode portion and another cathode layer; an anode terminal having a flat plate shape having a first surface and a second surface opposite to the first surface of the anode terminal, the first surface of the anode terminal being connected to the anode portion; an anode lead frame for joining the anode portion of the capacitor element with the another anode portion of the another capacitor element, the anode lead frame being connected to the first surface of the anode terminal; a cathode terminal having a flat plate shape having a first surface and a second surface opposite to the first surface of the cathode terminal, the first surface of the cathode terminal being connected to the cathode layer, the second surface of the cathode terminal being flush with the second surface of the anode terminal; a cathode lead frame for joining the cathode layer of the capacitor element with the another cathode layer of the another capacitor element, the cathode lead frame being connected to the first surface of the cathode terminal; and a resin package having an insulating property for accommodating the capacitor element, the anode terminal, and the cathode terminal, the resin package allowing the second surface of the anode terminal and the second surface of the cathode terminal to expose to an outside of the resin package, wherein the anode terminal includes a first thick portion and a first thin portion thinner than the first thick portion, the first thick portion having the second surface of the anode terminal and a portion of the first surface of the anode terminal, the first thin portion having a portion of the first surface of the anode terminal and being connected to the first thick portion, and wherein the cathode terminal includes a second thick portion and a second thin portion thinner than the second thick portion, the second thick portion having the second surface of the cathode terminal and a portion of the first surface of the cathode terminal, the second thin portion having a portion of the first surface and being connected to the second thick portion.
