PROBLEM TO BE SOLVED: To provide a clouding preventing system for an endoscope for preventing clouding of the endoscope inserted into a body cavity.SOLUTION: In one embodiment of the invention, the clouding preventing system for an endoscope includes a magnetothermal means disposed on a leading end side of the endoscope and an alternating magnetic field generating means separate from the endoscope. The magnetothermal means and the alternating magnetic field generating means are disposed in a close state within a range where an alternate magnetic field generated by the alternating magnetic field generating means acts on the magnetothermal means.COPYRIGHT: (C)2013,JPO&INPIT【課題】体腔内に挿入される内視鏡の曇りを防止する、内視鏡の曇り防止システムを提供する。【解決手段】本発明の一実施の形態では、内視鏡の曇り防止システムは、内視鏡の先端側に配置された磁気発熱手段と、内視鏡とは別体の交流磁場発生手段とを具備し、磁気発熱手段と交流磁場発生手段とが、交流磁場発生手段により発生された交流磁場が磁気発熱手段に作用する範囲内に近接した状態に配置される。【選択図】図1
