Object of the present invention is to provide a number of the electronic component mounting apparatus coping is possible in the case that reliably detect that after mounting operation of the electronic component to the printed circuit board, is held by the suction nozzle, and is held. Part or without having a line sensor unit 74 and the component recognition camera 83 for recognizing the position of the suction nozzle 15, suction holding an electronic component (D) as for the detection and suction position detection, and wherein the detection of whether the suction nozzle 15 to the suction holding the electronic component (D) of the printed board (P) in the mounting operation after the suction nozzle 15 to the electronic component (D) is held in support of the initially the line sensor unit 74 as if performing the detected that no is held on, said hold-down in the discharge box 82, e in the case of the component recognition camera that is held carried out with 83 detection part (D) It was installed the CPU (90) for controlling to skip the suction nozzle (15) for controlling at the same time to discharge. A line sensor unit, the suction nozzle, the component recognition camera, electronic components, exhaust box, CPU
