PROBLEM TO BE SOLVED: To provide a nasopharyngeal atresia stress distribution measuring instrument which is capable of simultaneously measuring the stresses in the localization where the soft palate comes into contact with the pharyngeal rear wall and a contact surface in order to analyze the human stomatognathic function, more particularly the power control function of the soft palate. SOLUTION: This nasopharyngeal atresia stress distribution measuring instrument is constituted by supporting sheets 45 and 47 so as to have flexibility in a casing, fixing a power transmission block 46 so as to project from the casing on these sheets and supporting a strain sensor 51 for measuring the perpendicular stress to the power transmission block in the casing to form a power sensor and linearly arraying a plurality of these power sensors on a flexible tape-like film. The instrument is arbitrarily localized held by the nasal fossa flank of the soft palate of the human body and the pharyngeal rear wall, by which the simultaneous measurement of the perpendicular stress distribution in the localization where the soft palate comes into contact with the pharyngeal rear wall and the contact surface is made possible.
