摘要： An object of the present invention is to provide a separator which is excellent in sticking and adhesion capability with the solid electrolyte, physically strong and highly heat-resistive and to provide a solid electrolyte condenser which is excellent in the impedance characteristic and leak current characteristic. In a solid electrolyte condenser comprising an anode foil, a cathode foil, a separator, the separator is made of a nonwoven fabric containing polyester resin or its derivative manufactured by the wet method. The condenser element is formed by rolling the anode foil and the cathode foil together with the separator between them. The solid electrolyte is provided between the anode foil and the cathode foil of the condenser element.
