PROBLEM TO BE SOLVED: To provide a silver compound metal powder suitable for fine wiring and formation of electrical contact points, and excellent in low-temperature baking characteristics in an atmosphere. SOLUTION: The compound metal powder consists of silver particles and particles of metal X other than the silver whose standard electrode potential E<SB>0</SB>is 0.80 V or higher, with average particle size (D<SB>TEM</SB>) as 20 nm or smaller while crystal particle size (Dx) as 20nm or smaller. It consists of compound particles including a mixed mode of silver particle and metal X particle, a mode in alloy particle of silver and metal X, a mode in core-shell structure with silver as a core and metal X as shell, a mode of core-shell structure with metal X as core and silver as shell, a carrying mode in which silver particle carries metal X particle, or carrying mode in which metal X particle carries silver particle.
