<P>PROBLEM TO BE SOLVED: To provide a device for measuring pulse wave, which performs pulse wave measurement, considering a state other than the pulse of a living body and the depth within the living body of a measurement object. <P>SOLUTION: The device includes: a living body sensor unit which emits one type of light selected from a plurality types of lights different in main wavelength from the body surface toward a blood vessel within the body and detects a volume pulse wave based on the reflected light; and a vibration giving unit which gives a vibration according to the volume pulse wave detected by the sensor unit into the blood vessel in the body. Since the behavior of the blood to which a vibration different from the pulsation of the heart is given can be acquired for a measurement depth corresponding to each of the plurality of types of lights, new data which can be used as an analysis object can be obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
