We show that the PAMELA anomaly in the positron fraction as well as the ATIC/PPB-BETS excesses in the e^-+e^+ flux are simultaneously explained in our scenario that a hidden U(1)_H gauge boson constitutes dark matter of the Universe and decays into the standardmodel particles through a kinetic mixing with an U(1)_<B-L> gauge boson. Interestingly, the B-L charge assignment suppresses an antiproton flux in consistent with the PAMELA and BESS experiments, while the hierarchy between the B-L symmetry breaking scale and the weak scale naturally leads to the right lifetime of O(10^<26>) seconds.
