Abstract
One object is to increase the filling factor of magnetic particles and increase the evenness of distribution of the magnetic particles in a magnetic main body of a coil component. A coil component includes: a magnetic main body containing a resin and magnetic particles; and a coil conductor embedded in the magnetic main body. The magnetic particles include large-sized magnetic particles, middle-sized magnetic particles, and small-sized magnetic particles. The proportion of the volume of the large-sized magnetic particles to the total volume of all the magnetic particles is 70 vol % to 85 vol %, the proportion of the volume of the middle-sized magnetic particles to the total volume is 2 vol % to 28 vol %, and the proportion of the volume of the small-sized magnetic particles to the total volume is 2 vol % to 28 vol %. The particle size distribution of the small-sized magnetic particles overlaps that of the middle-sized magnetic particles.
