Abstract:
1. A solid electrolytic capacitor comprising: a capacitor element having an anode portion made of a valve metal, a dielectric layer made of an oxide of said valve metal, and a cathode portion made of a solid electrolyte layer; and a converting substrate being electrically connected to said capacitor element on its upper face and having an anode terminal and cathode terminal as a pair of electrode terminals for mounting the solid electrolytic capacitor on its lower face; wherein, in a specified region on a side end face of said converting substrate, a plated anode fillet forming portion and plated cathode fillet forming portion are formed which control fillets formed when said anode terminal and said cathode terminal on the lower face of said converting substrate are each soldered to a corresponding portion of a circuit substrate, whereby the solid electrolytic capacitor is mounted on said circuit substrate.
