摘要： The present invention provides a method for producing an electrolytic capacitor including a porous body of a valve metal, an oxide film on a surface of the valve metal, and a conductive polymer layer on a surface of the oxide film. The step of forming the conductive polymer layer on the surface of the oxide film includes the steps of dipping the porous body in a monomer solution; lifting the porous body from the monomer solution and dipping the porous body in an oxidizing solution; and lifting the porous body from the oxidizing solution and allowing the porous body to stand. In the step of dipping the porous body in the oxidizing solution, a period for which the porous body is dipped in the oxidizing solution is equal to or shorter than a period in which 30% of the monomer contained in pores of the porous body diffuses and flows into the oxidizing solution. Alternatively, the volume of the oxidizing solution can be less than three times that of the porous body. The above method can be performed by replacing the monomer solution and the oxidizing solution with each other. Furthermore, a temperature of the porous body is maintained at a low temperature (e.g., 10.degree. C. or less) in the step of dipping the porous body in the oxidizing solution.

摘要： A method for testing a precursor of a secondary cell with high reliability and high efficiency to judge the precursor to be acceptable or defective. The current flowing when a test voltage is applied between a pair of electrodes is measured before an electrolyte is placed between the electrodes. If a current the current value of which exceeds a predetermined reference current value (13) is detected during the time from the start of application of a voltage to a normal secondary cell precursor until the current becomes constant, the precursor is determined to be defective.
