An initial mass function of main sequence stars in the solar neighbourhood is derived from the recent input data on luminosity function, and lifetime of main sequence stars. The luminosity function is corrected for the possible multiplicity of the stellar systems which are counted as single stars in a photographic plate. The mass function shows several humps indicating possibly the multimodality of star formation, and resolves the missing mass problem in a satisfactory manner.
