ABSTRACT:
This endoscope device is provided with: a laser light source that emits light having a specific wavelength; a diffusion optical component that diffuses light emitted from the laser light source and irradiates it onto an endoscopic examination subject at a distal end portion of an insertion portion; an adaptor that has a fluorescent substance that uses light from the laser light source as excitation light to emit light having a different wavelength, and is mounted on the distal end portion of the insertion portion such that it is able to be freely attached or removed; and a diffusion prevention component that is placed between the fluorescent substance of the adaptor and the diffusion optical component, and that prevents diffusion of light irradiated from the diffusion optical component.
