Abstract

An inductor manufacturing method includes a first step of press bonding a Cu foil onto a non-magnetic resin sheet, a second step of forming a conductor pattern by performing etching on the Cu foil, a third step of press bonding another non-magnetic resin sheet onto the conductor pattern, and a via conductor formation step of forming a via conductor that penetrates through the other resin sheet and leads to the conductor pattern. The method further includes a step of forming a body in which resin having magnetism is provided outside of a coil, by press bonding magnetic-powder-containing resin sheets onto a multilayer body, obtained by a manufacturing method including the first to third steps and the via conductor formation step, and then thermally curing the magnetic-powder-containing resin sheets.
