PROBLEM TO BE SOLVED: To provide an intrusion detection device capable of detecting an intruder in small moves and has high detecting accuracy with fewer erroneous detection. SOLUTION: The intrusion detection device has a pressure sensitive means 14 and a calculating means 152 for calculation on the basis of output voltage of the pressure sensitive means 14 to output calculated results. The pressure sensitive means 14 is a means to be mounted on a section to be touched by the intruder such as an upper surface of a wall-like structure, a handrail 12 or the like. The pressure sensitive means 14 is stored in a mounting section 13a and movable section 13b, and outputs voltage so that the pressure sensitive means 14 is deformed by bending the movable section at the intrusion.
