In the measuring device, in which the intake passage on the air cleaner side is connected to the main intake passage and the bypass passage of the throttle body at a substantially right angle on the upstream side of the throttle body, the partition wall is cut out at the upstream end face of the throttle body. An intake air flow measuring device for an internal combustion engine, characterized by:
