Abstract:
1. A method for producing an encoder including a stationary member and a movable member capable of movement relative to the stationary member, the encoder detecting the movement of the movable member relative to the stationary member, the method comprising: a body formation step in which at least one of the bodies of the stationary member and the movable member is injection-molded by an insulative material of a synthetic resin containing a nanoscale compound; an electro-conductive layer formation step in which an electro-conductive layer is laminated on the surface of the body; and a peeling step in which the electro-conductive layer is peeled off at a predetermined pitch to form an electrode pattern including the predetermined pitch; and an arranging step in which the movable member and the stationary member are arranged with the movable member movable relative to the stationary member to form an encoder that detects movement of the movable member relative to the stationary member, wherein the nanoscale compound is any one of carbon nanoscale compounds represented by carbon nanofiber or carbon nanotube.
