<p>A method of forming a conductor pattern, in which a conductor pattern formed on a support plate can be completely transferred from the support plate into a resin layer, and in which the step of roughening the surface of conductor pattern can be avoided to thereby attain reduction of production cost. In the method of forming a conductor pattern, there is provided conductor pattern (12) of overhung section having small-diameter part (12A) and large- diameter part (12B) superimposed on the superior surface of support member (100) sequentially from the superior surface toward vertical above. Subsequently, semi-hardened resin layer (110) is applied onto the support member (100), so that the conductor pattern (12) of overhung section is embedded in the resin layer (110), and the semi-hardened resin layer (110) is completely hardened. Thereafter, the resin layer (110) is detached from the support member (100) with the use of the large-diameter part (12B) of the conductor pattern (12) of overhung section as an anchor, so that the conductor pattern (12) of overhung section is transferred from the support member (100) into the resin layer (110).</p> |
