PROBLEM TO BE SOLVED: To realize a manufacturing method, for a contact probe, in which the strength of the probe is high and in which the probe can be easily made fine. SOLUTION: A resin layer 5, with which an oxidizing agent is mixed, is formed on a printed circuit board 1. A patterning operation is performed, in such a way that a resist is left on an electrode pad 3 on the printed circuit board 1 by a lithographic technique. Parts other than the required part are removed up to the halfway parts through wet etching operation. In addition, a dry etching operation is performed so as to perform patterning operation. Then, a monomer for a conductive polymer is polymerized in the resin, and a conductive layer is formed into a pattern.
