A first deformation sensor is arranged in a shock transmission member which is built in a vehicle and which constitutes a transmission path of a shock applied from the outside. A second deformation sensor is arranged in an exterior member which is exposed to the outside of a vehicle. Each of the first and second deformation sensors comprises a main body of sensor which has an elastomer and spherical conductive fillers blended in the elastomer in an approximately single particle state and with a high filling rate, and in which an electric resistance increases as an elastic deformation increases, and an electrode which is connected with the main body of sensor and is able to output the electric resistance.
