Abstract:
1. A method of manufacturing a chip type solid electrolytic capacitor comprising a capacitor element having an anode lead and a cathode layer, a packaging resin covering said capacitor element and having a mount surface and side surfaces adjacent to said mount surface and opposite to each other, an anode terminal electrically connected to said anode lead and coupled to said packaging resin, and a cathode terminal electrically connected to said cathode layer and coupled to said packaging resin, said method comprising: preparing a lead frame having an anode terminal-forming portion and a cathode terminal-forming portion; forging to form a stepwise shape in a part of said anode terminal-forming portion; connecting said anode lead to said anode terminal-forming portion; connecting said cathode layer to said cathode terminal-forming portion; covering said capacitor element with a packaging resin excepting a part of said anode terminal-forming portion and a part of said cathode terminal-forming portion; and cutting out said chip type solid electrolytic capacitor from said lead frame.
