PROBLEM TO BE SOLVED: To provide a detection and an indicator representation of vibration, using a vibration detecting sensor which can detect the vibration or the amount of vibration. SOLUTION: The vibration indicator is provided with: a bar-shaped movable electrically conductive body which swings when the vibration is applied, a fixed electrically conductive body for contact which is provided so as to contact with one end part of the movable conductive body; a fixed conductive body for fulcrum support which supports the swing fulcrum of the movable conductive body; a vibration detecting circuit which detects the vibration by the contact or release and the contact resistance changes between the movable conductive body and the fixed conductive body for contact, by arranging so as to locate the center of gravity of the movable conductive body on the side of the fixed conductive body for fulcrum support; and an indicator which indicates the variations in the amount of the vibration by the output signals of the vibration detection circuit.
