Dark photons have been considered potential candidates for dark matter. Thedark photon dark matter (DPDM) has a mass and interacts with electromagneticfields via kinetic mixing with a coupling constant of $\chi$. Thus, DPDMs areconverted into ordinary photons at metal surfaces. Using a millimeter-wavereceiver set in a radioshielding box, we performed experiments to detect theconversion photons from the DPDM in the frequency range 10--18 GHz, whichcorresponds to a mass range 41--74 $\mu\mathrm{eV}$. We found no conversionphoton signal in this range and set the upper limits to $\chi <(0.5\text{--}3.9) \times 10^{-10}$ at a 95% confidence level.
