    • A load sensor has a sensing unit which includes an excitation coil (2) and a solid rod magnetic body (1) provided along the axis of the excitation coil (2). The magnetic body (1) is magnetized by the excitation coil (2) and a load (P) is exerted on the magnetic body (1) to produce an inductance change from which the load (P) is measured. With this constitution, the construction of the sensor is simplified, a high strength can be obtained, the range of the load is widened, and the size, weight and cost of the sensor can be reduced. Therefore the sensor is easy to handle and portable. Since the load (P) is measured based on the change of inductance caused by the change of permeability of the magnetic body (1), the measurement is free from variation, a high direct feeling and feeling properties can be obtained, the adjustment of the sensor is easy, the hysteresis of the sensor is small, and the measurement is hardly influenced by magnetism.
