This article reports on the analysis of the first M31 survey with the ROSAT PSPC performed in July 1991. The spectral characteristics of the 396 individual x‐ray sources detected will be discussed as well as their positional correlation with the 108 individual x‐ray sources detected by the Einstein observatory. The optical identifications of the ROSAT x‐ray sources are the result of a MIT‐MPE‐UvA collaboration. A detailed analysis of the integral flux distribution shows that just two thirds of the detected x‐ray sources in the field of M31 must be background objects. The discovery of a significant absorption of background radiation is discussed, as well as an upper limit for the luminosity of a diffuse emission component. Finally a comparison of the luminosity function of 29 globular clusters sources with the one in our own galaxy reveals a good agreement.
