Solid electrolytic capacitor and its manufacturing method

A solid electrolytic capacitor comprising:

• (A) a capacitor element comprising:
• a dielectric oxide layer formed on a part of an outer surface of an anode body of a valve metal having a roughened surface layer thereon;
• a solid electrolyte layer formed on said dielectric oxide layer;
• a cathode formed of a conductor layer formed on said solid electrolyte layer;
• and
• an anode lead out area provided on a remaining part of the outer surface of said anode body;
• (B) lead terminals connected to the cathode and the anode lead out area of said capacitor element;
• and
• (C) a packaging resin encapsulating said capacitor element with parts of said lead terminals exposed outside,
• wherein (1) a first separation strip and a second separation strip are formed between said cathode and said anode lead out area and (2) an insulating material is disposed on the surfaces of said first and said second separation strips.
