1. A method of fabricating a solid electrolytic capacitor comprising a solid electrolytic capacitor element, a package covering the element, and an anode terminal and a cathode terminal for electrically connecting to an object;
wherein the solid electrolytic capacitor element comprises:
an anode member which is made of a valve action metal and extends in a longitudinal direction of the element, the anode member being provided with an anode portion and an anode lead portion;
a dielectric layer made of a metal oxide of the valve action metal and formed on a surface of the anode portion; and
a cathode member comprising a cathode conducting portion formed on a surface of the dielectric layer; and
wherein the method comprises:
preparing the solid electrolytic capacitor element;
applying an insulating resin member to cover the element;
forming hole portions in the insulating resin member; and
placing a metal-plating layer in the hole portions to provide the anode terminal and the cathode terminal;
wherein the applying of the insulating resin member comprises sandwiching the element between resin sheets.
