摘要：
A hard powder 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 a powder containing 90 vol % or more of a complex carbonitride solid solution represented by (Ti1-x,Mx)(C1-y,Ny), 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 of Ti and M, y represents an atomic ratio of N based on the sum of C and N, x and y satisfy 0.05≦x≦0.5 and 0.01≦y≦0.75.
