This is to provide hard powder which contains much amount of a complex carbonitride solid solution, which can improve sinterability of a sintered hard alloy and give a uniform structure. The hard powder is powder containing 90 vol% or more of a complex carbonitride solid solution represented by (Ti 1-x ,M x )(C 1-y ,N y ) [wherein M represents at least one element selected from the group consisting of W, Mo, Nb, Zr and Ta, x represents an atomic ratio of M based on the sum ofTi and M, y represents an atomic ratio ofN based on the sum of C and N, x and y each satisfy 0.05≦x≦0.5 and 0.01≦y≦0.75.]. |
