Abstract

Provided is an unprecedented and innovative wiring formation method with which it is possible to form transfer wiring using a transfer mold on a substrate having recesses and protrusions on the surface, without carrying out a smoothing process. The wiring formation method includes filling recesses () arranged in a prescribed pattern in a transfer mold () having the recesses () with an electroconductive member (), laying the transfer mold () filled with the electroconductive member () over the surface of a substrate () having recesses and protrusions, transferring the electroconductive member () to the surface of the substrate (), and forming a wiring part () on the surface of the substrate () using the electroconductive member (), wherein a soft mold having a durometer A hardness of 40-70 is used as the transfer mold ().
