PROBLEM TO BE SOLVED: To provide a data transmission system for a reliable wireless measurement signal at high-speed in tens of megabits or more per second from a rotating object to the non-rotating measuring instrument in the high resolution measuring for axial torque associated with the rotation of the high-speed rotating object. SOLUTION: The transmission method between the rotating object and the non-rotating object, as the data transmission system, is performed by leak electromagnetic field coupling of a strip line nonresonant transmission line terminated by the terminating resistance, in which the strip line structure is formed in a circular arc shape in direction toward the rotation circumference of the axis of the rotation on a printed board with a pattern, by placing the rotating object opposite to the non-rotating object, the broadband, for enabling the high-speed data transmission in the tens of megabits or more per second, and the stable transmission characteristics accompanying the rotation are attained and the transmission method is achieved.
