PROBLEM TO BE SOLVED: To provide a manufacturing method of a low-cost solid electrolytic capacitor having improved uniformity of thickness. SOLUTION: In a process for forming a solid polymer electrolyte layer 14a in an elemental intermediate body M1, the elemental intermediate body M1 is dipped into a liquid tank 30 for storing a polymerizing liquid P1 and is pulled out, thus adhering the polymerizing liquid P1 onto the element intermediate M1. An interval d1 between a first inner wall surface 30d and a second inner wall surface 30e of the liquid tank 30 is very narrow and is slightly larger than the thickness of the elemental intermediate body M1. Hence, the polymerizing liquid P1 in the liquid tank 30 has large surface tension. As the surface tension becomes larger, the polymerizing liquid P1 adhering to the elemental intermediate body M1 is pulled strongly toward the liquid surface, when the elemental intermediate body M1 is pulled out from the liquid surface. As a result; and while the element intermediate M1 is being pulled from the liquid surface, the surplus polymerizing liquid P1, adhering to the elemental intermediate body M1, can be pulled back to the inside of the liquid tank 30 by the surface tension.
