Abstract: The first core includes a main body part extending in a first direction along a main surface of the substrate, a first foot part extending from the main body part to the second core through the substrate, and a second foot part extending from the main body part to the second core through the substrate at a position at which the coil conductor is sandwiched between itself and the first foot part in the first direction, and the insulating member includes a bottom wall part interposed between at least the first foot part and the second core, and a side wall part extending along at least either of the first foot part and the second foot part and interposed between either of the foot parts and the coil conductor.
