To provide an intrusion detection device that can be easily mounted, has less influence of rain or snow, has a weather resistance, and can cope with various shapes. In the intrusion detection device of the present invention, pressure sensitive means ( 14 ) that is a flexible cable-like piezoelectric sensor is stored in a packet ( 13 ) in a sealed state, and mounted on a wall-like structure ( 11 ) such as a veranda, a balcony or a fence for the domicile. Since the packet is slidable, the pressure sensitive means is sufficiently deformed when the wall-like structure ( 11 ) is pressed, so that the sensor can make the detection reliably.
