Abstract:
1. A microscopic particle decentralized solution having decentralized microscopic particles with different diameters, wherein: the microscopic particle decentralized solution has two peaks in a granularity distribution, at a large diameter and a small diameter; microscopic particle mixtures satisfying the following relationships are decentralized in the solution; where R is a large particle diameter, r is a small particle diameter, N is the number of large particles, and n is the number of small particle, wherein the large diameter particle and the small diameter particle are conductive material selected from a group consisting of Ag, Cu, Au, Pd, Pt, Ni, W, Mo, or Cr, or its oxide, or its alloy, and a decentralizer layer is formed on the surface of the small diameter particle.
