Claim Text:
1. An inductor manufacturing method for manufacturing an inductor having a helical built-in coil formed of a conductor pattern and a via conductor, the method comprising: a first step of press bonding a first conductor layer onto a first non-magnetic material layer composed of a non-magnetic resin; a second step of forming the conductor pattern by performing etching on the press-bonded first conductor layer; a third step of press bonding a second non-magnetic material layer composed of a non-magnetic resin onto the conductor pattern; a via conductor formation step of forming a via conductor penetrating through the first non-magnetic material layer or the second non-magnetic material layer and leading to the conductor pattern; and a step of forming a body in which a resin having magnetism is provided outside a coil by subjecting a multilayer body having a built-in coil, and obtained by a manufacturing method including the first step to the third step and the via conductor formation step, to the steps of:
