Abstract: Motivated by the anomalous positron flux recently reported by the PAMELAcollaboration, we study the cosmic-ray positron produced by the pairannihilation and the decay of superparticle dark matter. We calculate thecosmic-ray positron flux and discuss implications of the PAMELA data. We showthat the positron excess observed by the PAMELA can be explained with some ofthe superparticle dark matter.
