%X We report on a search for hidden photon cold dark matter (HP CDM) using a novel technique with a dish antenna. We constructed two independent apparatuses: one is aiming at the detection of the HP with a mass of  ∼  eV which employs optical instruments, and the other is for a mass of  ∼ 5×10<sup>−5</sup> eV utilizing a commercially available parabolic antenna facing on a plane reflector. From the result of the measurements, we found no evidence for the existence of HP CDM and set upper limits on the photon-HP mixing parameter χ.
