Abstract

This invention provides a composite powder with high relative permeability, which improves the DC superposition characteristics of coil components having a hardened core containing the composite powder. The composite powder comprises a metal powder and a resin composition. The metal powder is a soft magnetic material. The resin composition comprises a thermosetting resin. The D50 of the metal powder is 15 μm or more and 21 μm or less. The D90 of the metal powder is 35 μm or more and 48 μm or less.
