Emission in the J = 1-0 line of CO has been mapped along the major axis of the large edge-on Sb galaxy NGC 4565. The shape of the CO distribution is very similar to that of the radio continuum emission, and of the disk light. The CO emission is much more centrally peaked than is the H I, but the total (H I+H2) gas surface density may have a smooth radial distribution. The total molecular hydrogen mass is similar to that of the H I. The asymmetry seen in the H I emission in this galaxy is also seen in the CO emission, implying that the ''lopsidedness'' of this galaxy is present at relatively small radii and high disk densities.
