Zusammenfassung:A component measurement apparatus includes: a sensor module that receives reflected light and outputs a signal corresponding to light intensity of the reflected light; a calibration plate that outputs first reflected light to the sensor module, the first reflected light being used for comparing the light intensity of the reflected light; and a calibration unit that switches the input reflected light to the sensor module between the second reflected light reflected at a measured portion, and the first reflected light.
