PROBLEM TO BE SOLVED: To provide an invasion warning device which emits a warning and sequentially lights ceiling illuminations as if a person is present in a building when an invader invades into the building from outside, immediately repulses the invader and previously prevents invasion. SOLUTION: Invasion sensors 2a-2d installed in plural rooms are connected to a warning controller 4. An illumination controller 9 which sequentially lights ceiling illuminations aN-a1 toward the room where the invasion sensor 2a operates from a room and a hallway in places detached from the room where the operated invasion sensor 2a is installed is connected to the warning controller 4. A timer for sequentially lighting/turning off the ceiling illuminations aN-a1 in the room and the hallway, which are viewed from outside, at every prescribed time at normal time when the invasion sensors 2a-2d do not operate is installed in the illumination controller 9.
