Abstract
A watch-type biometric measuring device having a pulse wave sensor unit for detecting a pulse rate by a reflective optical sensor, a housing 10 storing therein the sensor unit, and a wristband 20 is improved. The wristband 20 has short band pieces 21 and 23 near the housing 10, and long band pieces 22 and 24 far from the housing 10. The band pieces 21 and 23 have high flexibility, and permit movement of a living body. On the other hand, the band pieces 22 and 24 have low flexibility, and secure holding ability against the living body. With this configuration, it is possible to mount the biometric measuring device on a measurement site of the living body with high adhesion while minimizing the sensation of pressure.
