The invention provides a kind of Metal microparticle composite, it possesses membranaceous matrix resin and is fixed on the metal particle in this matrix resin, metal particle is by obtaining metal ion or metal salt back, the particle diameter of the metal particle of overall more than 90% is within the scope of 10nm ~ 80nm, disperse along the direction, face parallel with this surface in the scope of the degree of depth of this metal particle within from the surface of matrix resin to 150nm and form metal microparticle layer, and in this metal microparticle layer, the metal particle with above-mentioned particle diameter only exists 1 in the depth direction, adjacent metal particle be spaced apart more than the particle diameter of larger metal particle. |
