<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a wiring circuit board, capable of efficiently removing static electricity charged on an obtained wiring circuit board while preventing discoloration of a terminal portion. <P>SOLUTION: A circuit-equipped suspension board 1 provided with a metal supporting board 2, a base insulating layer 3, a conductor pattern 4 and a cover insulating layer 5 is prepared. Subsequently, a plating layer 8 is formed on the surface of a terminal portion 7, the circuit-equipped suspension board 1 is immersed in a polymerization liquid of a conductive polymer having redox potential lower than standard electrode potential of a conductor material configuring the conductor pattern 4, thereby forming a semi-conducting layer 10 on the surface of the base insulating layer 3 and the surface of the cover insulating layer 5. <P>COPYRIGHT: (C)2008,JPO&INPIT |
