PROBLEM TO BE SOLVED: To provide a powder for electrical conductive filler excellent in conductivity, obtained at low cost ad having light weight.SOLUTION: A material of particle 1 of a powder for electrical conductive filler is a Si-based alloy. The alloy contains Si of 50 mass% to 95 mass% inclusive, a conductive metal X and inevitable impurities. The alloy has a Si single phase 2 and a silicide phase 3. The silicide phase 3 contains Si and metal X. The density of the powder is 2.0 Mg/mto 6.0 Mg/minclusive. The metal X is one or more selected from a group consisting of B, Na, Mg, Al, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ag and Au. The cumulative 50 vol.% particle diameter (D) of the powder is 1 μm to 60 μm inclusive.SELECTED DRAWING: Figure 1 |
