The nickel oxide powder material is used in an anode material constituting a solid oxide fuel cell and is characterized in that spinel compound represented by compositional formula: NiM2O4 wherein M represents a metal element is formed inside or on the surface of the nickel oxide powder or at the interface between the powder particles.
