A theory of the Stark effect based on Schroedinger's ideas is presented. (1) Positions of lines practically coincide with those obtained in the writer's old theory which gave an excellent agreement with experiment. (2) Intensity expressions are obtained in a simple closed form: (a) Components which, in the old theory, had to be ruled out by a special postulate now drop out automatically. (b) The computed intensities of the remaining components check the observed within the limits of experimental error.
