Abstract
In a pulse wave detecting device for detecting a pulse wave by use of an ultrasonic wave, in order to prevent attenuation of the ultrasonic wave caused by a gap formed between the pulse wave detecting device and the user's skin, a transmitter for generating an ultrasonic wave and a receiver are formed on a support substrate so as to protrude therefrom. Consequently, the transmitter and receiver contact a surface of the skin and no gap is formed between the surface of the skin and the pulse wave detecting device. A pulse wave detecting device high in detection accuracy is thus realized without the need for applying a gel between the skin and a detecting surface of the device.
