Surface-mount solid electrolytic capacitor and process for manufacturing the same

A surface-mount solid electrolytic capacitor comprising:

• a capacitor element including an anode chip body, an anode bar projecting from the anode chip body, and a cathode film formed on a periphery of the anode chip body;
• an anode lead terminal and a cathode lead terminal made of metal, the capacitor element being mounted on an upper side of the anode lead terminal and the cathode lead terminal;
• a package made of synthetic resin and hermetically sealing the capacitor element entirely;
• a stud fixed to the anode lead terminal and including an upper surface resistance-welded to the anode bar of the capacitor element;
• and
• a welding support provided at an upper portion of the stud, the welding support being provided at least on both a portion closer to the anode chip body and a portion farther from the anode chip body;
• wherein each of the lead terminals is embedded in a bottom portion of the package so that a lower surface of the lead terminal is exposed at a lower surface of the package, and the cathode film of the capacitor element is fixed to an upper surface of the cathode lead terminal by conductive paste;
• and
• wherein the welding support is supported by at least one of the stud and the anode lead terminal and so designed that the anode bar does not come close to the anode lead terminal during the resistance welding of the anode bar to the stud.
