Claim 2:
3. A copper alloy powder which contains Cr in an amount of 12 wt % or less and Zr in an amount of 3 wt % or less, with a balance being made up of Cu and unavoidable impurities, and which is characterized in that a coating film containing Si atoms is formed on the copper alloy powder, a Si concentration in the copper alloy powder with the coating film is 5 wt ppm or more and 700 wt ppm or less, when a 2p spectrum of Si is analyzed based on XPS analysis in the copper alloy powder with the coating film, a maximum peak intensity exists in a binding energy range of 101 to 105 eV, and, when analysis is performed based on Raman analysis in the copper alloy powder with the coating film containing Si atoms, a maximum scattering intensity value in a Raman shift range of 1000 to 2000 cm−1 exists in a range of 1200 to 1850 cm−1.
