<p><P>PROBLEM TO BE SOLVED: To provide an endoscope apparatus constituted so that a projection part is provided on a distal end surface of a distal end part body and heat of an LED provided in an adapter is surely and efficiently transferred to the distal end part side even when the distal end body is formed from a material of bad heat conductivity. <P>SOLUTION: The endoscope apparatus is provided with: a distal end part body 30; a projection part 30h formed on a distal end surface 30p; a through-hole 30c formed in the distal end part body 30; a heat transfer member 51 engaged with the through-hole 30c; an O ring 61 for energizing the heat transfer member 51 on the distal end side; an adapter body 140 with an LED 150 fixed; and a recessed part 140h formed on a rear end surface 140p of the adapter body 140. When the adapter 110 is fitted to a distal end part 21, a bottom surface 140t is abutted on a projection surface 30t and the rear end surface 140b is abutted on an engagement part 52 against energization to the distal end side by the O ring 61. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
