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.
Claims9
A coil structure comprising:
- a substrate including a coil conductor;
- a first core disposed on one main surface side of the substrate;
- a second core disposed on other main surface side of the substrate;
- and
- an insulating member made of an insulating material, wherein 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 the second foot part 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.
