Abstract
A coil component is constituted by a composite magnetic material containing alloy grains whose oxygen atom concentration in their surfaces is 50 percent or less, and resin, and also by a coil. The alloy grains are comprised of first alloy grains and second alloy grains which have different compositions and different average grain sizes. The coil component using the composite magnetic material does not require high pressure when formed.
