Abstract

A method of manufacturing a rotary scale to be fixed to a rotating shaft of a rotating member includes a first step of forming, on a scale substrate, a scale pattern and a mark indicating an outer shape of the rotating shaft positioned such that a center axis of the rotating shaft coincides with a center axis of the scale pattern, a second step of cutting a first area of the scale substrate including the mark and having a first width, and a third step of cutting a second area including the mark that remains after the cutting of the first area, having a length in a circumferential direction of the scale substrate shorter than that in the first area and having a second width narrower than the first width.
