Copper chromium oxide thin films have been deposited on glass, sapphire and mica substrates by dc magnetron sputtering method at substrate temperature 2000C. The structural analysis of the deposited films with GAXRD shows the (0 1 2) prominent reflection peak of CuCrO2 with vertical to c-axis as delafossite structure and surface morphology was studied by SEM. The optical and electrical properties of the films were studied by UV-Vis spectroscopy and Four probe resistivity measurements. The optical Transmission curves reveal that the film deposited on glass substrate has high transmittance with maximum band gap energy Eg 3.02 eV. The electrical resistivity values were found minimum in sapphire
