A metal microparticle composite is provided, which includes a film-shaped matrix resin and metal microparticles immobilized in the matrix resin. The metal microparticles are obtained by reducing metal ions or metal salts, and the particle diameters of at least 90% of all the metal microparticles are in the range of 10 nm to 80 nm. The metal microparticles that are dispersed in a plane direction parallel to the matrix resin surface in a range of depth within 150 nm from the matrix resin surface to form a metal microparticle layer, and only one metal microparticle having the diameter described is present in the direction of depth in the metal microparticles layer. The spacing between adjacent metal microparticles is greater than and equal to the particle diameter of the larger one of the adjacent metal microparticles. |
