The present invention relates to a method of manufacturing a solid electrolytic capacitor element comprising the steps of forming a semiconductor layer on the dielectric layer formed on surfaces of a plurality of anode bodies at one time, wherein a step of forming a semiconductor layer comprises repeating an electrolytic polymerization operation several times by applying a current from a power-feeding terminal that comes into contact with each anode body, and at least one of the electrolytic polymerization operations continuously applies a current while changing the amount of current between the range of 5 to 200 µA per power-feeding terminal; and a jig for electrolytic polymerization for forming a semiconductor layer on the dielectric layer formed on a surface of an anode body, comprising a plurality of power supply circuits (i) provided on an insulating substrate and capable of continuously changing the amount of current between a lower limit and an upper limit; and a power-feeding terminals (ii) electrically connected to the output of each of the plurality of power supply circuits to be placed in contact with anode bodies. According to the present invention, a group of capacitor elements having high humidity resistance can be obtained by forming a semiconductor layer at one time on the dielectric layer formed on a plurality of anode bodies by electrolytic polymerization with a high impregnation rate. |
