Coil component

A coil component comprising:

• a body including a magnetic material;
• a substrate disposed in the body;
• a coil unit including
• first and second coil patterns disposed on both surfaces of the substrate, respectively,
• first and second via pads connected to inner ends of the first and second coil patterns, respectively, and
• a via connecting the first and second via pads to each other;
• and
• first and second external electrodes disposed to be spaced apart from each other on the body, while respectively being connected to the coil unit,
• wherein the first and second via pads include connection portions extending from innermost ends of the first and second coil patterns, respectively, in a direction toward the center of the first and second coil patterns,
• each of the first and second via pads has substantially the same or smaller line width than each of the first and second coil patterns, and
• a ratio L1/2R of a length L1, in a direction from the innermost ends of the first and second coil patterns toward the center of the first and second coil patterns, of each of the connection portions to a diameter 2R of the via is more than 0.02 and less than 1.30.

• wing portions protruding from both side surfaces of the connection portions, and
• a via connecting the first and second via pads to each other,
• wherein each of the wing portions has substantially the same or smaller line width than each of the first and second coil patterns,
• the line width of each of the wing portions is along a direction from the innermost ends of the first and second coil patterns toward the center of the first and second coil patterns, and
• the connection portion of the first via pad and the wing portion of the first via pad intersect each other in an inverted T-shape.
