Abstract: A mounting machine includes a head that includes a suction nozzle, the head being configured to suck a component at a distal end portion of the suction nozzle and mount the component on a board, a sensor that includes a light source and a light receiver, the light source being configured to emit a light ray to the distal end portion of the suction nozzle, the light receiver being configured to receive the light ray emitted from the light source, the sensor being configured to output light intensity of the light ray received by the light receiver, and a controller that computes a first differential value by differentiating the light intensity of the light ray output from the sensor, and determines whether or not a suction state of the component sucked to the distal end portion of the suction nozzle is defective based on the computed first differential value.
