PROBLEM TO BE SOLVED: To provide a duct with a sensor in which the sensor incorporated in a channel deflecting part can be normally operated. SOLUTION: This duct with the sensor is provided with a duct main body 2 in which an airflow A circulates from one end side toward the other end side, an airflow meter 3 as the sensor incorporated in a part near the downstream of the channel deflecting part 1 in the duct main body 2, and a protective wall 4 arranged in a part near the upstream of the channel deflecting part 1 and covering the airflow meter 3 when viewed from one end side of the duct main body 2. The airflow A is regulated by the protective wall 4, thereby the turbulence of the airflow A around the airflow meter 3 is suppressed, and the output variation of the airflow meter 3 is made within allowable extent in practical use.
