Abstract
A purpose is to provide a resin encoder scale a cost of which can be reduced by making processing easy by producing the encoder scale as a resin molded piece including a scale pattern. A resin encoder scale is used in a reflection-type optical encoder and a scale pattern for position measurement is provided thereto. In the scale pattern, a low reflection part a surface of which is molded as a rough surface during resin molding and which has low reflectivity of light and a high reflection part a surface of which is molded as a mirror surface during the resin molding and which has higher reflectivity of light than the low reflection part are arranged alternately.
