PROBLEM TO BE SOLVED: To simply and accurately measure pressure distribution of the surface, without damaging the object to be measured. SOLUTION: A device for measuring pressure distribution fixes to bond a flexible sheet-like pressure detection member 11 opened with pressure detection holes 11b for each of a plurality of pressure passages 11a that extend in parallel on the surface of an outer plate 16, in order to measure the pressure distribution of the surface of the outer plate 16 of a main wing W of an airplane, and connects each pressure passage 11a to a pressure measuring device 20 via pressure piping 17, arranged in the main wing W. Since the pressure detection hole 11b is opened in the pressure detection member 11 and need not be opened to the outer plate 16 of the main wing W, will not only not damage the outer plate 16, but also the flexible sheet-like pressure detection member 11 is properly fitted to the surface of the outer plate 16 of a three-dimensional curve face, since the thickness is thin, the flow of an air stream is hardly disturbed, and measurement accuracy of the pressure distribution is enhanced.
