There are 15 flare stars, out of the 70 known, detected by IRAS at 12 micron; they are Point Source Catalogue objects. Half of them show weak 25 micron emission as well. Five more flare stars are confirmed by coadding the survey data in the IRAS file. The 12 micron luminosity L(12) of the detected stars is in the range of 0.2-4 x 10 to the 30th erg/s. Only 0.6 percent of their bolometric luminosity L(bol) is emitted in the far infrared, with the exception of four stars for which this fraction is 1-2 percent of L(bol). Strong correlation is found to exist between L(12) and L(bol) and it is expressed by L(12) = 10 exp -208 L(bol). It is concluded that IRAS has detected the photospheres of the brightest nearby flare stars. For two of them, though, there is some indication of small IR excess, which, if real, could be due to circumstellar matter of a thin dust shell.
