We have searched for the supersymmetric partner of the photon, the photino, by investigating two-photon and single photon final states in e+e− collisions. No significant signals were observed, which excludes the existence of the photino in the mass range 0.08–18 GeV/c2 at the 95% confidence level, subject to the assumptions d=(100 GeV)2 and , where d is the supersymmetry breaking scale parameter and is the scalar electron mass.
