PROBLEM TO BE SOLVED: To provide an endoscope capable of measuring the size of an object of observation without contact. SOLUTION: As the light 52 in a prescribed pattern is irradiated parallel to the object 48 of observation from each light transmitting part 32 via each microlens 34 in the endoscope 10, the light 52 is irradiated on the object 48 of observation in the prescribed pattern. Further, as the object 48 of observation and the light 52 irradiated on the object 48 of observation are imaged by an imaging element 28 and the images are displayed on a monitor 50, the size of the object 48 of observation can be easily measured by comparing the object 48 of observation and the pattern of the light 52. At the time, it is not necessary to bring the distal end 12A of an insertion part 12 into contact with the object 48 of observation in measuring the size of the object 48 of observation, so that the deformation and breakage of the object 48 of observation can be prevented.
