PROBLEM TO BE SOLVED: To provide a respiratory state during sleep measuring apparatus with which a respiratory state of an examinee during sleep can be precisely measured without the influence of a change of a temperature such as the temperature of a room or the like in the lapse of time. SOLUTION: The apparatus includes a respiration sensor 3, which is disposed at least at one of the nostril 2a and the mouth of the examinee and detects a change of air pressure due to flowing in and out of respiratory air through the above nostril 2a or the mouth caused by the respiration, and a respiratory information analyzing means which analyzes the respiratory information from the above information of the change of the air pressure detected by the above respiration sensor 3.
