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.
