This paper reports a detection of the 30 micron emission feature from the C-rich Asymptotic Giant Branch (AGB) star IRAS 03313+6058 based on the ISO-SWS observation. Modeling of the spectral energy distribution shows that this emission starts at about 20 micron and possibly extends to the limit (45 micron) of the observation. By assuming MgS as the carrier, the number ratio of Sulfur atom in MgS to Hydrogen atom in total, n(S)/n(H), is 3. 10{-6} from model fitting. A comparison of this emission feature is made with other AGB and post-AGB objects.
