Abstract
An inductor includes an external terminal and an element body that includes a magnetic portion containing a magnetic powder and a coil embedded in the magnetic portion. The magnetic powder has a particle size D50 at 50% of the cumulative volume of 5 μm or less, a D90/D10 of 19 or lower, and a Vickers hardness of 1000 (kgf/mm) or lower, the D90/D10 being the ratio of particle size D90 at 90% of the cumulative volume to particle size D10 at 10% of the cumulative volume in the cumulative particle size distribution by volume. In the magnetic portion, the packing density of the magnetic powder by volume is 60% or higher.
