Abstract: 
PROBLEM TO BE SOLVED: To make a first aging treatment performable on the capacitor elements of an organic solid electrolytic capacitor, without deteriorating the productive efficiency even when a short-circuited capacitor element exists. SOLUTION: In a method for manufacturing organic solid electrolytic capacitor, the shells of capacitor elements 1 for an organic solid electrolytic capacitor, in which anode leads 10 are protruded from anode bodies and conductive layers 11 are arranged on cathode layers, are formed by performing the first aging treatment on the element 1 and the organic solid electrolytic capacitor is manufactured by performed the second aging treatment. The process for performing the first aging treatment in the manufacturing method includes a step of respectively arranging the elements 1 on a plurality of carbon sheet pieces 3 which are arranged in such a way that the pieces 3 are not electrically connected to each other so that the conductive layers 11 of the elements 1 may come into contact with the pieces 3, a set of connecting the anode lead 10 of each element 1 to the positive pole of a power source 6, a step of connecting each piece 3 to the negative pole of the power source 6 through a current limiter 5, and a step of impressing a voltage upon the elements 1 from the power source 6.
