Inside an endoscope air sending device (15), an air compressor (13), an air tank (34), an air filter (35), a pressure control valve (38), a pressure sensor (14), and a discharge valve (12) are provided so that those elements form a closed space therein. An air sending fan (47) is provided on the wall of a housing (10), and a circuit board (K) is provided above the air sending fan (47) and those elements forming the closed space. A discharge outlet (60) is provided on the housing (10) in such a manner that the discharge outlet (60) is located above the circuit board (K).
