We studied thin films of the Dirac semi-metal Cd3As2, about 100 nm thickness, made by vacuum thermal evaporation from cadmium arsenide single crystals. The temperature and magnetic field dependences of the electrical resistance were measured, which indicate the presence of a superconducting transition at a temperature between 0.2 to 0.6 K.
