A detailed map of the distribution of the [CII] 158 mu m line intensity from the galactic plane around l = 50(deg) was obtained by the Far-Infrared Line Mapper (FILM) on board the Infrared Telescope in Space (IRTS). The distribution of the [CII] emission is similar to that of the far-infrared continuum emission. There are a number of discrete sources, most of which correspond to known objects, such as compact HII regions and molecular clouds, near to the galactic plane. Moreover, an extended component concentrated in the galactic plane was found, and its distribution does not clearly depend on the galactic longitude in the observed area. This extended component decreases rapidly as the galactic latitude increases. The FWHM of this component is about 2.(deg) 6 in the galactic latitude. This is larger than that of the CO (J=1 -> 0) intensity, but is much smaller than that of the HI 21 cm intensity.
