A layered pressed and sintered anode body consisting of a support body of a tungsten-molybdenum alloy having a first layer of tungsten or tungsten alloy on the surface which is impinged by electrons and having a second layer of a higher melting point material on the other side whose tensile strength at the elastic limit is greater, at temperatures of 1400.degree. to 1600.degree. C, than the tensile stresses occurring at these temperatures to avoid warping of the anode.
