Document Type and Number:
WIPO Patent Application WO/2014/068612
Kind Code:
A1
Abstract:
Provided is a production method for a coil element, whereby a resin mold can be used and the thickness of the coil element can be reduced without peeling away or transfer. The production method for the coil element uses a resin mold capable of being dissolved in an organic solvent, said method having: a step in which the resin mold having an inverse coil element pattern stamped on the surface thereof is prepared; a step in which a metal seed film is formed on the surface of the resin mold; a step in which the metal seed film in an area having no inverse coil element pattern formed therein is removed; a step in which a central conductive film is formed by using a first electroplating and by using the metal seed film as the foundation therefor, said film filling in the area having the inverse coil element pattern stamped therein; and a step in which the resin mold is dissolved and the central conductive film is retrieved.
