PROBLEM TO BE SOLVED: To provide a human body detection device excellent in wrong detection prevention, while having a simple constitution. SOLUTION: Sensor blocks 1A, 1B or the like are stored in an internal space enclosed by a body 13 and a cover 14. The sensor blocks 1A, 1B are constituted of infrared detection elements 2A, 2B and reflecting mirrors 3A, 3B, and stored in an apparatus body in the form wherein angles of reflecting surfaces of the reflecting mirrors 3A, 3B with respect to the apparatus body are mutually differentiated in the vertical direction. The widths of detection beams BM1, BM2 or the interval between the detection beams BM1, BM2 can be set individually according to the shape, the size or the like of the reflecting surface of each reflecting mirror 3A, 3B, and this human body detection device excellent in detection error prevention, while having a simple constitution compared with a conventional sample comprising a plurality of infrared detection elements and one reflecting mirror, is provided.
