In medical situation, a self breathing holding method using no breathing monitoring device shows inferior accuracy in holding breathing by a patient with poor understanding of the self breathing holding method. In view of the above, development of a readily understandable breathing holding method and breathing monitoring device with high accuracy has been desired. A breathing monitoring device having a multi-point detector comprises a housing mounted to a treatment couch for a patient to lie thereon, so as to cover the patient's body, such as a chest, an abdomen, or the like; a displacement amount determination unit mounted to the housing, for determining displacement amounts of at least two points on the patient's chest and abdomen; and a respiration level determination unit for determining a combined displacement amount which is a combination of the displacement amounts determined of the patient's chest and abdomen due to respiration.
