Disclosed is a vibration detecting device capable of accurately detecting vibration regardless of the position of an object to be measured, without alignment with a part of the human body to be measured. A case has a sufficient size to be mounted to a part of the human body to be measured. In an embodiment, since it is assumed that a vibration detecting device is worn on a user's wrist, the case has a ring shape with a sufficient size to be worn on the user's wrist. Rubber, which is an elastic material, is provided in the case, and piezoelectric elements are provided inside the rubber. The piezoelectric element is an electric field changing unit that changes an electric field using the vibration of an object to be measured. Electric field sensors that detect the electric field are provided on the outer surface of the case. |
