Abstract
In the coil component, the thickness of the first coil portion and the thickness of the second coil portion are different from each other in the thickness direction of the substrate, thereby achieving improvement in characteristics such as self-resonance frequencies and heat dissipation.
Claims7
A coil component comprising:
- an element body;
- a substrate disposed inside the element body;
- a coil conductor including a first winding portion provided in a planar spiral shape on one surface of the substrate, a second winding portion provided in a planar spiral shape on the other surface of the substrate, and a penetration portion penetrating the substrate and connecting end portions of the first winding portion and the second winding portion to each other;
- and
- a pair of terminal electrodes provided on a surface of the element body and connected to the first winding portion and the second winding portion of the coil conductor, respectively,
- wherein when a thickness of the first winding portion in a thickness direction of the substrate is a first thickness and a thickness of the second winding portion is defined as a second thickness, the first thickness and the second thickness are different from each other.
