The problem of flare activity frequency among red dwarf stars is discussed. The observational data on stars in Orion, Pleiades and solar vicinity are used. It is shown, that relative number of flare stars among all red dwarf stars in the considered samples is increasing towards the lower luminosity stars. The flare stars are found in the considered samples begining with a definite luminosity, this limiting luminosity being decreased with the aging of the system which includes flare stars. A possible explanation of the observed phenomenon is given.
