Beschreibung
Zusammenfassung:	The present invention provides a noble metal alloy powder which has both high crystallinity and composition uniformity. This noble metal alloy powder is formed of an alloy of five or more noble metal elements, and has an average particle diameter of 10 [mu]m or less and a crystallite size of 80 nm to 140 nm. With respect to the X-ray diffraction spectrum of this noble metal alloy powder, one peak is found within the diffraction angle 2[Theta] range of 38 DEG to 44 DEG.
