Abstract
An optical adaptor for endoscope according to the present invention includes, in an outer casing, a light emitter, serving as a light source for illumination, and two terminals connected to the positive and negative electrodes of the light emitters to be externally projected from the inside of the outer casing. The connection of a diode between the positive and negative electrodes of the light emitters prevents the static electricity from being applied to the light emitter.
