<P>PROBLEM TO BE SOLVED: To provide an endoscope apparatus that can provide a good observation performance by reducing the generation of flares caused by a fact that the light from an illumination window directly enters an observation window. <P>SOLUTION: The endoscope apparatus includes an illumination window 41 for causing illuminating light to exit and an observation window 45 for obtaining an image of a subject, at an end face 67 of an endoscope insertion part that is inserted into the subject. The illumination window 41 is an illuminating lens having a positive-power light exit surface. The relationship between the maximum projection height Hi of the illumination window 41 that projects in the axial direction of the endoscope insertion part from the end face 67 of the endoscope insertion part and the maximum projection height Ho of the observation window 45 satisfies Ho≥Hi. <P>COPYRIGHT: (C)2012,JPO&INPIT |
