PROBLEM TO BE SOLVED: To provide a comfortable burglar-proof device for maintaining burglar-proofness, and realizing energy saving by using an opening. SOLUTION: This burglar-proof device is configured of a magnetic body installed in a sliding door type fitting for opening/closing the opening of an external wall, a magnetic sensor for detecting magnetic change due to the movement of the magnetic body accompanied with the opening/closing operation of the fitting and an alarm unit for executing a burglar-proofing operation when an electric signal generated according to the detection of the magnetic change of the magnetic sensor is transmitted. The burglar-proof device is configured by forming the position of the magnetic sensor slidable in the same direction as the moving direction of the magnetic body, and constituting the fitting of aluminum sashes, and provided with a base mountable on a rail so as to be freely attachable/detachable, a supporting pole erected from that and a preventing tool arranged at the upper edge, and constituted of a lock receiving part to be engaged with the engagement lug of a crescent lock arranged at the fitting.
