A human body exercise sensor to indicate a consistent reaction value regardless of arrangement angle of the sensor is provided to prevent the chattering phenomenon by grinding both end of a vibrator to be shape. A human body exercise sensor comprises: a vibrator(101) of four each horn-based; a signal terminal(100) arranged at both end part of the vibrator with specific interval; and a case(103) surrounding the sensor. One end part of the vibrator is made of material having heavy specific gravity and has two times bigger volume than the other end part. The vibrator is tenuously surrounded with light metal material into one body. A convex protrusion is molded at a site where a signal terminal contacts the vibrator. The inside and outside of the signal terminal are plated with gold. The signal terminal includes a wire and electrically connected to a current applying circuit.
