Definitions

  • the method of the present invention is effective when applied to an electric conductor having a CV value of 1,000 ⁇ F-V/cm 2 or more where pores having a depth of 200 ⁇ m or more are produced by etching. It is possible to directly connect an outgoing lead wire to the electric conductor.
  • a part of a separately prepared outgoing lead (lead wire or lead foil) may be shaped together with the electric conductor and the outgoing lead outside the shaped portion may be used as the outgoing lead of one electrode of the capacitor.
  • the sintered bodies were washed with water and dried.
  • the resulting sintered body excluding the lead wire was dipped in a 15% ethanol solution of 3, 4-ethylenedioxythiophene monomer, pulled up and dried at 80°C to dissipate the ethanol, thereby impregnating pores of the sintered body with the semiconductor layer-forming precursor.
  • Comparative Example 2 216 Chip solid electrolytic capacitors (produced from 432 capacitor elements where the semiconductor layer was relatively successfully formed) were produced in the same manner as in Example 2 except that the concentration of the ethylenedioxythiophene alcohol solution used was changed to 20%, an operation of alternately dipping the sintered body in this solution and in an alcohol solution of 18% iron naphthalenesulfonate without further dipping it in alcohol was repeated 30 times to form a chemical polymerization layer on the electric conductor having provided thereon a dielectric layer, and the impregnation of pores of the sintered body with a semiconductor layer-forming precursor was not performed.
  • the capacitance, impregnation ratio, ESR value and LC value of each of the capacitors produced above were measured by the following methods.
