N1 - Funding Information:
One of the authors (F.T.) was aware that there is another group working independently on a scenario using a hidden gaugino [32] . This work was supported by World Premier International Center Initiative (WPI Program), MEXT, Japan. The work of S.S. is supported in part by JSPS Research Fellowships for Young Scientists.

N2 - We study a scenario that a U (1) hidden gaugino constitutes the dark matter in the Universe and decays into a lepton and slepton pair through a mixing with a U (1)B - L gaugino. We find that the dark-matter decay can account for the recent PAMELA and ATIC anomalies in the cosmic-ray positrons and electrons without an overproduction of antiprotons.
