Let f(z, z̄) be a mixed polar homogeneous polynomial of n variables z = (z1, . . . , zn). It defines a projective real algebraic variety V := {[z] ∈ CP | f(z, z̄) = 0} in the projective space CP. The behavior is different from that of the projective hypersurface. The topology is not uniquely determined by the degree of the variety even if V is non-singular. We study a basic property of such a variety.
