摘要

The resin-metal composite 100 includes resin particles 10 and metal particles 20. The metal particles 20 are dispersed or fixed in the resin particles 10, and a part of the metal particles 20 is three-dimensionally distributed in the surface layer portion 60 of the resin particles 10. The metal particle 20 includes an encapsulated metal particle 30 completely encapsulated in the resin particle 10, a partially exposed metal particle 40 having a part embedded in the resin particle 10 and a part exposed outside the resin particle 10, and a resin And surface adsorbing metal particles 50 adsorbed on the surfaces of the particles 10.
