    • A major objective of the present invention is to provide a magnetically enhanced resin and the like having an improved magnetic permeability. The magnetically enhanced resin contains a ferromagnetic material, a compound having a macrocyclic π electronic structure, and an adhesive resin. The ferromagnetic material is preferably a powder of a Fe—Ni alloy, a Fe—Ni—Mo alloy, a Fe—Ni—Cu alloy, or a Fe—Al—Si alloy. The ferromagnetic material is preferably a powder of permalloy, supermalloy, sendust, or ferrite. The compound having a macrocyclic π electronic structure is preferably phthalocyanine, porphyrin, or polycyanine, a substitution product thereof, or a metal coordination complex thereof. The adhesive resin is preferably an epoxy resin, a melamine resin, a polyimide resin, a polycarbonate resin, a phenol resin, or a fluorosilicone resin. The average particle size of the powder of the ferromagnetic material is preferably 0.1 to 100 μm.
