Summary:PROBLEM TO BE SOLVED: To precisely measure component concentration by precisely detecting a sonic wave occurring in a subject by reducing influence of noise. SOLUTION: Light is emitted intermittently to the subject, and the intensity of the emitted light is made higher than that in the case of emitting light continuously. When an irradiation time to the patient is short, the light can be intensified and emitted. In the case of emitting intense light, the sound wave occurring in the subject is increased by a component to be measured, and the component concentration is measured precisely while a signal-to-noise ratio is large. Moreover, the sonic wave and the noise mixed to the sonic wave are detected and the noise is subtracted from the sonic wave to precisely detect the sonic wave occurring in the subject by the component to be measured.
