PROBLEM TO BE SOLVED: To provide an electronic stethoscopic apparatus capable of reducing noise that can be mixed in continuously monitoring a sound from a living body such as a vital sign.SOLUTION: An electronic stethoscopic apparatus 1 for detecting a biological sound includes a biological sound sensor attached to a living body directly or indirectly for detecting a biological sound continuously, and a cover member 31 attached separately from the biological sound sensor for reducing the noise mixed into the biological sound sensor by physical stimulation from the outside to the biological sound sensor. The cover member 31 is provided with an aperture part 32 for further reducing the noise mixed into the biological sound sensor by physical stimulation.SELECTED DRAWING: Figure 3
