CO(J=1−0) line observations of the southern arm of the barred-spiral galaxy M83 were made with the 45-m telescope of the Nobeyama Radio Observatory with a 17″-beam. The CO emission is concentrated to the spiral arm, but it is much weaker than in the bar. The comparison between the CO flux and the far ultraviolet flux suggests the star forming efficiency is much lower in the bar than in the spiral arm.
