Description of the Related Art A pulse wave of a person is directly attached to an earlobe with an optical sensor sandwiched therebetween, or an optical sensor is directly applied to a fingertip to amplify and measure an electric signal obtained from the sensor. This pulse wave is used as a heart rate monitor and an index of the physical and mental state. For example, Japanese Patent Application Laid-Open No. 10-071
No. 137, JP-A-07-313494, JP-A-07-051234, JP-A-62-25303
As described in, for example, Japanese Patent Publication No. 2 (1999), a technique has been devised in which the activity of the human autonomic nervous system is analyzed from pulse wave data and the mental and physical state of the human is estimated from the results.

った。[0003] Pulse waves can be divided into earlobe pulse waves and fingertip pulse waves. Earlobe pulse waves are governed by the sympathetic nervous system and parasympathetic nervous system, and fingertip pulse waves are governed mainly by the sympathetic nervous system. In order to estimate the state of mind and body of a human being, mainly using the fluctuation of the sympathetic nervous system as an index, the fingertip pulse wave is used in the conventional method. However, the conventional fingertip pulse wave sensor is sensitive to external light and restricts the movement of the finger. Therefore, there is a great restriction in using the fingertip pulse sensor as an index for estimating the physical and mental state during work.

め、センサ装着自体がストレスとなってしまう。[0005] As described above, the earlobe pulse wave sensor can be used to measure the earlobe pulse wave to estimate the mental and physical condition of a person. However, the earlobe pulse wave sensor is also sensitive to external light, and the pulse wave is not detected. Since the person to be measured is made aware of the measurement, the mounting of the sensor itself becomes a stress.
