摘要： An object of the present invention is to improve the adhesive property of the solid electrolyte of a solid electrolytic capacitor where a solid electrolyte layer has an electrically conducting polymer to provide a solid electrolytic capacitor favored with mechanical strength, high capacitance, low impedance, good humidity resistance load characteristics and excellent heat resistance. The present invention provides a solid electrolytic capacitor having a dielectric film on the surface of a valve-acting metal having fine pores, a solid electrolyte layer, an electrically conducting carbon paste layer and an electrically conducting metal powder paste layer in order. The binder of the electrically conducting carbon paste is allowed to infiltrate into the solid electrolyte layer formed on the dielectric film on the surface of the valve-acting metal or into the solid electrolyte layer and the inside of the fine pores. The present invention also provides a method for producing the capacitor.
