Effects of finite resistivity, η, on gravitational instability are investigated in magnetohydrodynamical approximation. It is shown that resistivity has a stabilizing effect on this instability. Main approximations used are : (1) small resistivity, v/L²<<ω₀, where ν=c²η/4π, L=|B/∇B|≡L_Bor|ρ/∇ρ|≡Lρ, and ω_o²=g (1/L_B+1/Lρ); (2) strong mgnetic field, ω_A>>ω_o andP<<B²/8π where ω_A is Alfvén frequency. Two cases are examined where plasma is partially ionized (v∞1/ρ) and fully ionized (v∞T^-3/2).
