PROBLEM TO BE SOLVED: To provide an acceleration sensor property evaluation device which reduces cost of manufacture.SOLUTION: An acceleration sensor package attitude holding unit 1 is configured to hold an attitude of an acceleration sensor package P in any one of two predetermined attitude states. Fixed-length links 3-1 and 3-2 and a variable-length link 3-3 of which a length (r) is e.g., 50 mm are connected at three points of a table 2 for fixing the acceleration sensor package attitude holding unit 1. The links 3-1, 3-2 and 3-3 are parallel with one another and are infinitely rotatable with respect to rotary shafts 4-1, 4-2 and 4-3 thereof as shown by arrows R1, R2 and R3. When the rotary shaft 4-1 is rotated by a drive motor 5, a perfect uniform circular motion can be performed with the length (r) of the links 3-1, 3-2 and 3-3 as a radius as shown by an arrow R0. An angle signal &thetas; of the uniform circular motion is detected by a rotary encoder 6 provided in the rotary shaft 4-1.
