Abstract
The capacitor element includes a porous chip body and an anode wire having an end portion embedded in the chip body. The chip body includes a surface provided with a dielectric film which in turn is formed with a solid electrolyte layer thereon. Further, the solid electrolyte layer is laminated with a cathode film. The chip body is formed by sintering a mixture of valve metal powder and a sintering inhibitor added as impurities. Similarly, the anode wire is made of valve metal containing a sintering inhibitor.
