Abstract
A soft magnetic resin composition contains flat soft magnetic particles, and a resin component containing an epoxy resin, a phenol resin, and an acrylic resin. The epoxy resin consists of only an epoxy resin having three or more functional groups, the phenol resin consists of only a phenol resin having three or more functional groups, and the content ratio of the acrylic resin in the resin component is 25 mass % or more.
