摘要：
A rotary encoder of the present invention has a hermetically sealed structure having at least one desiccant and an electric circuit by which the moisture absorbing amount of the desiccant can be obtained. The desiccant is arranged in a sealed space defined by a flange and a cover member. The electric circuit, a rotary slit plate, a light emitting element and a light receiving element are arranged in the sealed space.
