A shock sensor includes an inductance coil, a magnet, a magnetically soft material, and a support bracket for the magnetically soft material. The inductance coil and the magnet are fixed relative to each other. The magnetically soft material has one side thereof fixed on the support bracket and lies relative to the coil and the magnet so that the magnetically soft material can move up and down as well as leftwardly and rightwardly and inwardly and outwardly when the shock device vibrates and thereby alter a magnetic flux from the magnet to the inductance coil so as to generate signals responsive to the fluctuations of a magnetic flux.
