Abstract
The present invention addresses the problem of providing a stethoscope having a structure which enables even physicians working remotely to recognize whether the chest piece of the stethoscope is touching the surface of the body appropriately. A stethoscope provided with: a stethoscope portion (10) comprising a chest piece and a microphone provided within the chest piece or in a hollow tube connecting to the chest piece; and sensors (20a-20c) for detecting contact with a human body, wherein the sensors detect contact by abutting with the body, and are fixed to the chest piece such that, when in a state detecting contact, the abutting ends of the sensors are situated in the same position as the contact surface of the chest piece against the body or in a position that is separated slightly farther from the body than the contact surface.
