We investigate the minimum mass of brown dwarfs using radiation hydrodynamics simulations of collapsing filamentary clouds and analytical estimates. We found the minimum mass of brown dwarfs depends on the initial temperature of parent clouds and the nature of heating sources. The universal minimum mass of brown dwarfs, which is about 0.007M⊙, is given when the initial cloud temperature is 13.3 K. Our results are consistent with recent observations of low-mass objects in some star forming regions.
