Abstract: A bilirubin concentration measurement system including: a sensor device attachable to a subject; and a terminal device capable of wirelessly communicating with the sensor device. The sensor device includes: a light emitting diode that emits blue light; a light emitting diode that emits green light; a light detection diode that detects reflected light that is the blue light having been incident on skin of the subject and reflected, and detects reflected light that is the green light having been incident on the skin of the subject and reflected; and a communication unit that wirelessly transmits information about intensities of the reflected light detected by the photodiode. The terminal device includes: a communication unit that receives the information about the intensities of the reflected light transmitted from the sensor device; and a computing unit that calculates a bilirubin concentration using the information about the intensities of the reflected light.
