Some possible signatures of the neutral Higgs meson H˚ of the standard electroweak theory are investigated. We find that (1) The polarization measurement of the final fermion pair in e^+e^- → ff can give definite signature of H” and (2) The present known 0^(++) mesons can not be the candidate of H˚. We also calculate the cross sections for l^+l^- → Z˚H˚, and l^+l^- → Z˚H˚H˚ and find that the Z˚ angular distribution takes a simple from A + Bcos^2θ. Thus the measurement of the Z˚ angular and the energy distribution can give definite signature of H”.
