SOFT MAGNETIC FERRITE RESIN COMPOSITION, SOFT MAGNETIC FERRITE RESIN COMPOSITION MOLDED BODY, AND POWER TRANSMISSION DEVICE FOR NON-CONTACT POWER SUPPLY SYSTEM

摘要

The present invention addresses the technical problem of providing a power transmission device for a non-contact power charging system that has high power transmission efficiency and high impact resistance. This problem is solved by the following: a molded body of a soft magnetic ferrite resin composition comprising a filler material and a binder material, wherein the filler material is a soft magnetic ferrite powder having a mean grain size of 5 to 35 μm, the binder material is one or more types selected from thermoplastic resins and soft polyolefin resins, the molding density of the molded body of the soft magnetic ferrite resin composition is 3.2 to 4.7 g/cm³, and the magnetic permeability is 5 to 15; and a power transmission device for a non-contact power supply system using the molded body of a soft magnetic ferrite resin composition.
