Observation of the high-velocity flows in the core region of the NGC7538 molecular cloud are carried out with CO (J=1-0) molecular line using NRO 45-m radio telescope. The beam size is 14″ and the mapping area covers about 4'x3′. Four high-velocity flows are found in the core region. The high-velocity flows are prominent at and around IRS1, 9, and 11.
