Abstract
An inductor is provided so that reduction in DC superposition characteristics can be suppressed even when a filling rate of a magnetic powder is increased. The inductor includes a coil including a winding portion and a pair of extended portions extended from the winding portion, and a body having the coil embedded therein and containing a magnetic powder containing a first magnetic powder and a second magnetic powder, in which an average particle diameter of the first magnetic powder is larger than an average particle diameter of the second magnetic powder. In a cross section of the body including a winding axis of the winding portion and extending in a long side direction of the body, Voronoi partition is performed with a center of gravity of each magnetic powder as a generating point. When a standard deviation of an area of a Voronoi partition region with a magnetic powder having a particle diameter of equal to or more than 6 μm as a generating point is calculated, the standard deviation is equal to or less than 300.
