Stability of LIB implosion for the thermal instability is investigated in comparison with laser implosion. Several conditions on the thermal instability are drawn in n-T diagram. Essential unstable condition is A<n/n_s<B, where A=8.1×10^<-13>T[eV]^<8/3> (l_Nl_T)^<-1/3>, B=6.2×10^<-12> T[eV]^2 R/(l_Nl_T), n=4.5×10^<-12> m^<-3>, l_N[m] and l_T[m] are the scale lengths of number density and temperature. High density and low temperature plasma produced by LIB is less unstable than that produced by laser. This is confirmed actually by the results of simulation done at the Tokyo Institute of Technology.
