ーダ。 In an optical encoder that has a structure in which both rotating and fixed slit plates are arranged facing each other, a ring-shaped fixed slit made of glass material is adhesively fixed to the housing side. By applying several predetermined amounts at unevenly spaced angular positions, consideration is given so that the surface runout caused by curing shrinkage during adhesive curing will not affect the signal generation slit light transmitting part of the fixed slit. An optical encoder with the following features.
