Solid electrolytic capacitor and method for producing the same

A solid electrolytic capacitor comprising a molded body of a plurality of solid electrolytic capacitor elements each having an anode part assigned to one end part of an anode substrate composed of a valve-acting metal having on the surface thereof a dielectric film layer, and a cathode part including a solid electrolyte layer formed on the dielectric film layer in a remaining portion of the anode substrate and having an electrically conducting layer formed thereon, the anode parts and the cathode parts being stacked one on the other, the anode parts being connected to a lead frame via a weld metal provided on one or more of the anode parts of the solid electrolytic capacitor elements by irradiating the anode parts with a laser ray, and the stacked body being molded with an outer jacket resin.

A method for producing a solid electrolytic capacitor, which comprises providing an anode part at one end part of an anode substrate composed of a valve-acting metal having on the surface thereof a dielectric film layer, forming a solid electrolyte layer on the dielectric film layer in a remaining portion of the anode substrate and an electrically conducting layer thereon to provide a cathode part, thereby preparing a solid electrolytic capacitor element, providing a weld metal on the anode part, irradiating the anode part with a laser ray to connect it to a lead frame, and molding with an outer jacket resin.
