PROBLEM TO BE SOLVED: To provide a winding attitude evaluation device capable of more accurately evaluating winding attitude of a strip in the state that it is actually wound on a reel. SOLUTION: The winding attitude evaluation device 20 is a device for evaluating the winding attitude of a magnetic tape MT wound on the reel 2, and is provided with a radial height detection part for detecting radial height of an outer peripheral surface of the magnetic tape MT; and a winding attitude evaluation part 23b for evaluating the winding attitude based on the detected radial height. The radial height detection part is a laser type displacement sensor 22 provided with a projection part for projecting a linear laser light L over the whole of width of the magnetic tape MT; and a light-receiving part for receiving a reflected linear laser light L.
