Beschreibung
Zusammenfassung:	A method of manufacturing an inductor element includes preparing an insert member including a winding portion where a conductor is wound in a coil shape. A plurality of preliminary green compacts is obtained by conducting a preliminary compression molding of a granule containing a magnetic powder and a resin at a pressure of 2.5×102 to 1×103 MPa. The insert member and the plurality of preliminary green compacts are integrated so that a joint interface of the plurality of preliminary green compacts is formed intermittently.
