A throttle body (10) with a housing (12) comprising a housing cover (17) and a housing body (14) and with a through throttle aperture (20) for a throttle butterfly (26) arranged on a throttle-butterfly shaft (22), the throttle-butterfly shaft (22) being drivable as a function of specifiable parameters by an electronic system (56) arranged in the housing (12) by an electric actuator (32) likewise arranged in the housing (12) and having an actuator shaft (28), the position of the throttle-butterfly shaft (22) being detectable by a position detection device (70) arranged in the housing (12), is to have a particularly small space requirement and, at the same time, a contactless position detection device (70) for the throttle-butterfly shaft (22) For this purpose, the electronic system (56) for the electric actuator (32) is arranged in the housing cover (17), and the position detection device (70) comprises a Hall-effect magnet (76) arranged on the actuator shaft (28) and a Hall-effect sensor (72) arranged directly next to the Hall-effect magnet (76) for detecting the position of the throttle-butterfly shaft (22).
