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.

Abstract: A multilayer coil having a laminate body having a plurality of insulating layers including a specified insulating layer. A linear coil conductor is substantially looped on the specified insulating layer. An insertion is located on the specified insulating layer, in a position between a first part and a second part of the coil conductor. The first part and the second part are closest parts to each other in the coil conductor. Along a boundary surface between the first part of the coil conductor and the insertion, the first part is located at an upper side of the coil conductor with respect to a stacking direction.
