Latest Patents

Sumio Nishiyama holds a patent for a chip-type solid electrolytic capacitor and the method of manufacturing it. This invention includes a cathode conductive layer that is provided on the entire surface of a cathode layer formed on the outer surface of a capacitor element. The design ensures that when the capacitor element is obliquely inserted into a mold during the formation of a resin shell, the inner walls of the mold do not contact the cathode layer. Instead, they come into contact with the cathode conductive layer, preventing exposure of the cathode layer to the resin shell. This innovative arrangement helps to eliminate defects in electric characteristics, such as leakage of electric current and a tan.delta. value.
