Abstract
A functional material includes at least two kinds of particles selected from the group consisting of first metal composite particles, second metal composite particles and third metal composite particles. The first metal composite particles, the second metal composite particles and the third metal composite particles each contain two or more kinds of metal components. The melting point T(° C.) of the first metal composite particles, the melting point T(° C.) of the second metal composite particles and the melting point T(° C.) of the third metal composite particles satisfy a relationship of T>T>T
