Abstract
An oxide film 2 which is so modified as to hold hydrophobic groups 3 on its surface, and further to stabilize an anionic substance 6 among those hydrophobic groups, has an electroconductive polymer layer 7 formed thereupon. The electrolyte capacitor includes the adherence of the hydrophobic groups 3 and anionic substance 6 onto the surface of the oxide film includes exposing an element upon which the oxide film has been formed, to a steam of the hydrophobic group or to a solution containing the hydrophobic group, and then exposing the same element to a steam of the anionic substance or to a solution containing the anionic substance.
