PROBLEM TO BE SOLVED: To provide a technology for improving the measurement accuracy of a measurement apparatus for measuring the pressure or frictional stress applied to a to-be-measured part in a member to be measured. SOLUTION: The measurement apparatus 2 is provided with four beams 4a, 4b, 6a, 6b which extend from a back face of the to-be-measured part 8a; a linking plate 14 for linking them and formed with a thickness at which a distortion is generated by the pressure applied to the part to be measured 8a and has a local maximum; and four distortion sensors 10a, 10b, 12a, 12b provided to a lower face of the linking plate 14. A first group of the distortion sensors 10a, 10b measure distortions generated in the linking plate 14, in the direction of a first pair of the juxtaposed beams 4a, 4b. A second group of the distortion sensors 12a, 12b measure distortions generated in the linking plate 14 in the direction of a second pair of the juxtaposed beams 6a, 6b. The measuring apparatus 2 calculates the pressure or the frictional stress applied to the part to be measured 8a from the distortion measured by the distortion sensors 10a, 10b, 12a, 12b.
