Patent ID: 7433175

Claim:
A solid electrolytic capacitor comprising: an anode member which is made of a valve action metal, said anode member being provided with an anode portion and an anode lead portion; a first dielectric layer made of an oxide of the valve action metal and formed on lower and upper surfaces of said anode portion; a second dielectric layer made of an oxide of the valve action metal and formed on first side, second side, and third side surfaces of said anode portion, said first side and said second side surfaces being opposed to each other and perpendicular to said lower and said upper surfaces of said anode portion, said third side surface being perpendicular to said lower and said upper surfaces of said anode portion and positioned to make an angle with said first side and said second side surfaces; an electrical insulating resin layer formed on said second dielectric layer; and a cathode layer formed on said first dielectric layer and said electrical insulating resin layer.
