1. A pulse wave detecting device comprising:
- transmitting means for transmitting an ultrasonic wave toward an artery;
receiving means for receiving the ultrasonic wave transmitted by the transmitting means and reflected by the artery; and
a rigid support substrate on which the transmitting means and the receiving means are provided;
wherein the transmitting means and the receiving means protrude from a surface of the substrate, the surface being disposed while in use against a user'"'"'s skin.

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.

13. A pulse wave detecting device comprising:
- a support substrate disposable against a part of living body;
a transmitter provided on the substrate as to protrude from a first surface of the substrate for transmitting an ultrasonic signal toward an artery in the living body; and
a receiver provided on the substrate so as to protrude from the first surface of the substrate for receiving the ultrasonic signal transmitted by the transmitter and reflected by the artery;
wherein the transmitter and the receiver protrude from the first surface of the support substrate so that when the support substrate is placed in contact with the living body, the transmitter and the receiver are urged into close contact with the living body to thereby reduce attenuation of the ultrasonic signal that may otherwise be caused by an air gap formed between the support substrate and the living body.
