PROBLEM TO BE SOLVED: To provide a crime prevention sensor which can be installed in a wide range for surely detecting the damage of an intrusion port configuring member by reducing erroneous operations. SOLUTION: A crime prevention sensor 2 is provided with an elastically deformable sensor main body 20 with an elastomer and a spherical conductive filler blended in an almost single particle state by a high filling rate in the elastomer, and configured so that an electric resistance is increased according as deformation quantity is increased and electrodes 21A and 21B connected to the sensor main body 20 so that the electric resistance can be output, and this crime prevention sensor 2 is arranged at an intrusion port configuring member 90L configuring an intrusion port from the outside. The crime prevention sensor 2 is configured to detect the damage of the intrusion port configuring member 90L from the deformation of the sensor main body 20 accompanied with the deformation of the intrusion port configuring member 90L.
