A magnetic compact includes first magnetic particles, second magnetic particles with larger particle sizes than the first magnetic particles, and a resin. The area ratios calculated for multiple regions of the magnetic compact have a standard deviation of 0.40 or less, where area ratio=(total area of first magnetic particles)/(total area of second magnetic particles).

Magnetic compact and inductor

A ferrite core includes a ferrite sintered body in which integrally formed are a winding core portion, extending in a lengthwise direction, and flange portions provided at both ends in the lengthwise direction of the winding core portion and projecting from the winding core portion in at least a height direction orthogonal to the lengthwise direction. Pores are present inside the winding core portion and the flange portions, and an abundance ratio of the pores in the winding core portion is equal to or more than about 0.05% and equal to or less than about 1.00% (i.e., from about 0.05% to about 1.00%).
