A search for hidden photon cold dark matter in a mass range from 5 to 500 eV in data collected during 60 days in November and December, 2015 by a Multi-Cathode Counter (MCC) is reported. From the analyses of this data we found no evidence for the existence of HP CDM and set an upper limit on the photon-HP mixing parameter χ. This is the first result obtained by direct measurements in this mass range for hidden photon CDM using a single electron event in MCC as a signature.
