The endoscope cover is attached to the distal end configuration portion along the longitudinal axis of the insertion portion, and has an annular portion that covers a part of the outer periphery of the distal end configuration portion, and at least partially between the distal end configuration portion and the endoscope cover. A cylindrical cover body that is spaced apart and mounted with a gap between the front end constituent part, and at least a part of the annular part of the cover body is provided, and is stronger than other parts of the annular part. It has a fragile portion that is low and is broken when stress is applied, and that allows an operator to recognize that the tip has been broken in cooperation with the gap.内視鏡用カバーは、先端構成部に挿入部の長手軸に沿って装着され、先端構成部の外周の一部を覆う環状部を有するとともに先端構成部との間の少なくとも一部に対して離間し先端構成部との間に間隙を有して装着される筒形状のカバー本体と、前記カバー本体の前記環状部に少なくとも一部が設けられ、前記環状部の他の部位よりも強度が低く、応力が加えられることにより破壊されるとともに、前記先端構成部の前記間隙と協働して破壊されたことを作業者に認識させることが可能な脆弱部とを有する。
