An electronic scope capable of preventing reduction in the amount of light in a desired wavelength band is configured to be inserted into a body cavity, and includes: an insertion tube having a light emission port in its tip portion； a light guide configured to guide light down to the tip portion of the insertion tube to emit first light from the tip portion； and a light emitting device configured to emit second light from the tip portion, the light transmittance of the light guide for the wavelength band of the second light being less than or equal to the transmittance for the wavelength band of the first light. The light path length of the second light from the light emitting device to an emission port for the second light provided in the tip portion is shorter than the light path length of the first light in the light guide.
