PROBLEM TO BE SOLVED: To provide a crime prevention sensor for preventing appearance design property from being deteriorated since a handrail installed at the upper end section of the waist wall or fence or wall of a balcony section and a sensor cap piece for covering a pressure sensor, and for pressurizing the pressure sensor are separately viewed, and the installation of a crime prevention sensor is quite obvious. SOLUTION: The pressure sensor 1 is installed on the upper face of a handrail 83 installed at the upper end section of the waist wall or fence or wall of a balcony section, and the sensor cap piece 2 formed almost like a channel shape or almost like a U shape so as to be opened downward is installed so that the pressure sensor 1 and the handrail 83 including the lower end section can be covered from the upper part, and that the pressure sensor 1 can be pressurized when it is depressed due to the application of a downward load.
