PROBLEM TO BE SOLVED: To provide a biological signal detector provided with an attenuation means for attenuating the vibration of an air mat in the biological signal detector which measures pressure variation inside the air mat spread under a human body and detects body data such as the heart rate, respiration rate, turning frequency and snoring signal of the human body. SOLUTION: The attenuation means 2 attenuating the vibration of the air mat 1 is formed of an air room into which air flows freely and an elastic body disposed inside the air room and this means 2 is closely stuck to the air mat 1 or integrally formed therewith. Thus, the vibration of the air mat 1 can be attenuated in a short time, thereby influence of vibration generated before is saved and the reliability of the measured value of the biological signal detector using the air mat is improved. |
