Abstract
Provided are an elastomer composition including epoxy resin, acrylate resin, an organic filler, an inorganic filler, a cross linking agent, a hardener, an initiator and a solvent, and a magnetic ferrite for a wireless power transmitting and receiving device, the magnetic ferrite being coated with the elastomater composition having an elastic restoring force not to be damaged by a physical impact applied from the outside.According to embodiments of the present invention, the magnetic ferrite having improved impact resistance can be provided by being coating with the elastomer composition having the elastic restoring force, and thus an existing problem such as a reduction in magnetic property caused by damage to the ferrite resulting from an external impact can be solved.
