The feedback effect of supernova explosions on dwarf galaxies in the cold dark matter dominated universe is studied. A mass loss model of galaxies and a method of comparing the model with observations are developed. It is found that when a galaxy is surrounded by a dark halo, the mass loss caused by supernova explosions is severely restricted, but not as severely as was expected. if we assume the collapse redshift to be z = 2 ~ 8, the model agrees with the observations for the range of parameters chosen, and indicates that less massive galaxies are formed first.
