To enable a body-conduction sound sensor to be easily attached to a subject and to make it difficult for a body-conduction sound sensor to pick up sounds other than a body-conduction sound, to use a body-conduction sound sensor and an acceleration sensor in combination, Provided is an apparatus for measuring the heart rate and the respiration rate with high accuracy regardless of the condition of the subject.SOLUTION: The bar-shaped body 1 has a distal end portion that can be inserted under the armpit of a subject and the body-conduction sound sensor 2 is provided at the distal end portion thereof. The acoustic signal acquired by the body-conduction sound sensor 2 is acoustically A body sound signal processing means 3 for processing the heart rate and acoustic respiration rate by the heart rate measuring section 4 and the sound respiration rate measuring section 5 to obtain the subjects acoustic heart rate and acoustic respiration rate, A heart rate and respiratory rate measuring device comprising a notifying means (6) for displaying the respiration rate and informing the examiner or the subject.BACKGROUND OF THE INVENTION【課題】体導音センサを被検者に容易に装着できるようにし、かつ、体導音センサが体導音以外の音を拾いにくくすること、体導音センサと加速度センサを併用して、被検者の状態によらず、心拍数及び呼吸数の計測を高精度で行えるようにする装置を提供する。【解決手段】被検者の脇の下に挿入可能な先端部を有し、その先端部に体導音センサ2が設けてある棒状体1と、体導音センサ2によって取得された音響信号を音響心拍数計測部4及び音響呼吸数計測部5で処理して被検者の音響心拍数及び音響呼吸数を求める体導音信号処理手段3と、表示部7に求められた音響心拍数及び音響呼吸数を表示して検査者又は被検者に知らせる報知手段6を備える心拍数及び呼吸数計測装置。【選択図】図1
