PROBLEM TO BE SOLVED: To provide a distal end cover mounted on a distal end constituting part of an insertion device of an endoscope, prevented from falling and residing in a lumen, and preventing leak of a high-frequency current to the outside by close adhesion to the distal end constituting part.SOLUTION: The distal end cover of an endoscope includes a covering part mounted thereon for covering a distal end constituting part that is provided at a dital end of an insertion device of the endoscope, to be inserted into a lumen, the covering part having electrical insulating properties, and preventing leak of a high-frequency current. A holding part provided at an extension part extending to the dital side of the insertion device holds the outer periphery of the insertion part, so as to prevent falling and residing of the covering part.SELECTED DRAWING: Figure 1【課題】内視鏡の挿入機器の先端構成部に装着され、管腔内への脱落や残留を防止し先端構成部への密着により外部への高周波電流の漏出を防止する先端カバーを提供する。【解決手段】内視鏡の先端カバーは、管孔内に挿入する内視鏡の挿入機器の先端に設けられる先端構成部を覆うように、電気絶縁性を有し、高周波電流の漏出を防止する被覆部が装着される。被覆部は、挿入機器の先端側へ延出する延出部に設けられた保持部が挿入機器の外周を保持することにより、脱落や残留を防止される。【選択図】図１
