PROBLEM TO BE SOLVED: To provide an endoscope apparatus capable of reducing heat generation at an endoscope distal end part.SOLUTION: The endoscope apparatus includes: an endoscope insertion part 19 to be inserted to a subject a light emitting part 59 provided on a distal end part 33 of the endoscope insertion part 19 and including a phosphor and light sources LD2 and LD3 for supplying light to the light emitting part 59. The light source LD 2 emits blue light, the light source LD 3 emits red light, the light emitting part 59 is formed of one kind of phosphor which mainly emits green light with the blue light as excitation light, and the content of the phosphor occupying the light emitting part 59 is determined such that the intensity of the green light emitted from the light emitting part 59 and the intensity of the blue light transmitted through the light emitting part 59 roughly match.COPYRIGHT: (C)2013,JPO&INPIT【課題】内視鏡先端部分での発熱を低減することのできる内視鏡装置を提供する。【解決手段】被検体に挿入される内視鏡挿入部19と、内視鏡挿入部19の先端部33に設けられる蛍光体を含む発光部59と、発光部59に光を供給する光源LD2及びLD3とを備え、光源LD2は青色光を出射し、光源LD3は赤色光を出射し、発光部59は、青色光を励起光として、主として緑色光を発光する1種類の蛍光体によって形成されており、発光部59に占める蛍光体の含有量は、発光部59から発光される緑色光の強度と発光部59を透過する青色光の強度とが略一致するように決められている。【選択図】図2
