After sucessful tests of an SRF gun with a superconducting half-cell cavity (*), a new SRF photo-injector for CW operation at the ELBE linac has been designed. In this report the design layout of the SRF photo-injector, the parameters of the superconducting cavity and the expected electron beam parameters are presented. The SRF gun has a 3 1/2-cell niobium cavity working at 1.3 MHz and will be operated at 2 K. The three full cells have TESLA-like shapes. In the half cell the photocathode is situated which will be cooled by liquid nitrogen.
