Abstract
A coil component includes a support substrate having one surface including at least one groove portion; a coil portion disposed to contact the one surface of the support substrate; and a body embedding the support substrate and the coil portion, wherein the coil portion has an anchor portion disposed in the at least one groove portion, and a pattern portion disposed on the anchor portion and spaced apart from the one surface of the support substrate. A line width of the anchor portion is narrower than a line width of the pattern portion.
Claims21
A coil component comprising:
- a support substrate having one surface including at least one groove portion;
- a coil portion disposed to contact the one surface of the support substrate;
- and
- a body embedding the support substrate and the coil portion,
- wherein the coil portion has an anchor portion disposed in the at least one groove portion, and a pattern portion disposed on the anchor portion and spaced apart from the one surface of the support substrate,
- wherein a line width of the anchor portion is narrower than a line width of the pattern portion,
- wherein the coil portion has a plurality of turns, and
- wherein the anchor portion of one of the plurality of turns includes a plurality of anchors spaced apart from each other in a region where the line width of the pattern portion is defined.
A coil component comprising:
- a support substrate having one surface including first and second groove portions having different depths;
- a coil portion disposed on one surface of the support substrate;
- and
- a body embedding the support substrate and the coil portion,
- wherein the coil portion has first and second anchor portions respectively disposed in the first and second groove portions in the support substrate, and a pattern portion connected to the first and second anchor portions and protruding from the one surface of the support substrate,
- wherein the pattern portion is spaced apart from the one surface of the support substrate, and
- wherein a plurality of turns of the coil portion are spaced apart from each other in a cross-section of the coil component, and in the cross-section of the coil component, the first and second anchor portions extend from a same turn among the plurality of turns of the coil portion.
A coil component comprising:
- a support substrate;
- a coil portion including an anchor portion embedded in the support substrate, and a pattern portion extending from the anchor portion and protruding from the support substrate;
- a body embedding the support substrate and the coil portion;
- and
- an insulating layer disposed between the pattern portion and the support substrate,
- wherein an average roughness (Ra) of one surface of the coil portion facing the support substrate is greater than an average roughness (Ra) of another surface of the coil portion opposing the one surface of the coil portion.
