Patent ID: 8288458

Claim:
A functional resin material for use in injection molding, the functional resin material comprising a resin and a plurality of aggregates of functional particles, each of the aggregates of functional particles comprising a plurality of functional particles and an insulating material covering the plurality of functional particles, wherein the resin is nylon 6, and wherein the aggregates of functional particles comprise (1) an amorphous magnetically soft alloy powder of (Fe 0.97 Cr 0.03 ) 76 (Si 0.5 B 0.2 ) 22 C 2 having an average particle diameter of 20 Î¼m and a ferrite powder having an average particle diameter of 5 Î¼m as the functional particles, and an epoxy resin powder as the insulating material, or (2) an amorphous magnetically soft alloy powder of (Fe 0.97 Cr 0.03 ) 76 (Si 0.5 B 0.2 ) 22 C 2 having an average particle diameter of 150 Î¼m as the functional particles, and an oxide film as the insulating material.
