A luminous portion 12 is mounted on the inner surface of the left end portion of the gripping member 11A of the clip 11 and a receiving portion 13 is mounted on the inner surface of the left end portion of a gripping member 11B. While the ear is gripped with the clip 11, light emitted from the luminous portion 12 is transmitted through the ear 9 and received by the receiving portion 13. A transmitting portion 18 and a storage portion 19 are installed at the right end portion of the gripping member 11B, and the antenna 21 is connected to the transmitting portion 18, which is thereby connected to the main body by radio. The main body calculates an acceleration pulse wave by differentiating twice a digital volume pulse wave transmitted from the transmitting portion 18, and has a function to print or display it.
