Abstract
A solid electrolytic capacitor having a high capacitance and excellent high frequency response including a valve metal sheet which is made porous, a dielectric layer formed on the porous portion, a solid electrolyte layer formed on the dielectric layer, a collector layer and an electrode exposure area formed on the solid electrolyte layer, and an insulating section electrically insulating the electrode exposure area from the collector layer, in which the electrode exposure area and the collector layer are formed on the same surface of the valve metal sheet.
