PROBLEM TO BE SOLVED: To provide a method for manufacturing a wiring board for an electric test to be used for electrical inspection which requires contact continuity including continuity resistance test for high-density wiring boards such as printed boards, boards for integrated circuits, and liquid crystal display boards, etc. SOLUTION: A method for manufacturing a wiring board for an electric test is composed of an insulating board, wiring of a specified pattern buried in the insulating board, projecting electrodes provided on the wiring to touch the electrodes of a device to be tested, whrein the tips of the projecting electrodes made of an electrically conductive metal are covered with a conductive polymer. The manufacturing method for a wiring board for an electrical test comprises the steps of: burying in an arbitrary resin an electrolytic copper plating wiring pattern formed on a nickel layer by using two layer foils consisting of a carrier electrolytic copper foil and the nickel layer; setting a guide mark of the wiring formed so as to be viewed from the side of the carrier electrolytic copper foil; and forming the projecting electrodes by aligning the guide mark and the guide mark included in a negative image.
