Abstract: PROBLEM TO BE SOLVED: To provide a wind tunnel model dispensing with mark formation on each model and both calibration tests of a sensor and a magnetic force, by forming a mark to be provided inside the model on another body than a contour body in order to measure the position or the attitude of the model from the outside in a wind tunnel test of a magnetic force support type. SOLUTION: This wind tunnel model 1 for magnetic force support is equipped with the contour body 2 made of a transparent resin and formed to have a thin shell shape, and a mark body 3 installed inside the contour body 2 and having the mark 5 optically detectable through the contour body 2. The mark body 3 can be constituted by putting the mark 5 on the surface of a magnet body 4 performing magnetic interaction with lines of the magnetic force of a magnetic force support balance device provided in the wind tunnel. By constituting the mark body 3 separately from the contour body 2, the mark 5 formation on each model and the calibration tests on the sensor and the magnetic force can be omitted, and the wind tunnel model 1 can be manufactured at low cost and the wind tunnel test can be performed efficiently both in time and in cost system 5 of the light receiving element 6.
