Abstract ： Mapping observations were made towards IRAS 20110+3321 using the Nobeyama 45m and the Delingha 13.7m radio telescopes. The high angular resolution (～ 21'') image with the 45m telescope shows that there is a high-velocity bipolar molecular outflow in this region, which is in the NW--SE direction with a collimation factor of ～2.2. The outflow has significantly higher mass loss rate and mechanical luminosity than those from low mass YSOs, indicating that the outflow is driven by the IRAS source. A dense massive core was detected by mapping C18 O (J=1-0) line in the area with the 13.7m telescope. The IRAS source lies within the core but slightly offsets from its emission peak.
