Abstract
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).
