ABSTRACT:
An organism information measuring method and an arm wear type pulse-wave measuring method having a sensor unit having a size that does not cause any inconvenience to a user when the user is doing an exercise, such as jogging, so that information about an organism, such as the pulse rate, is measured. The arm wear type pulse-wave measuring apparatus has a wrist band for putting the body of the apparatus on the arm; and a sensor unit that is put on the root of a finger by a sensor securing band. If the finger is irradiated with light by a LED in the foregoing state, light reaches the blood vessel and is reflected. The reflected light is received by a phototransistor in such a manner that the quantity of received light corresponds to change in the quantity of blood occurring due to pulse waves of the blood. The LED is of a type capable of emitting blue light and has a light emission wavelength peak of 450 nm. The phototransistor has a light receiving wavelength region in a range from 300 nm to 600 nm.
