An exhaust hood is provided to readily collect and suck the air separated toward an outer periphery of a hood main body to suppress separation of air flow flowing along an outer surface of a curved wall. An exhaust hood includes a hood main body(110), a suction fan, and a front collecting part(140). The hood main body includes a canopy(111), and an exhaust part(121). The canopy has a suction part for sucking the air. The exhaust part is in communication with the canopy to discharge the air sucked through the suction part. The suction fan is installed in the hood main body to blow the air. The front collecting part includes a supply nozzle(141), and a suction nozzle(145). The supply nozzle is formed at a front end of the canopy to discharge the air blown by the blower fan. The suction nozzle is disposed at the downstream of the supply nozzle in an air flow direction of the air discharged through the supply nozzle to suck the air.
