ABSTRACT:
An endoscope hood has a protrusion portion which protrudes in an observation visual field direction of an endoscope at an end of a cylindrical press fitting fixing portion attached by press fitting in a state that an attachment position in a circumferential direction is positioned at a distal end portion of an endoscope insertion portion in an appropriate direction. Further, there is provided attachment state confirming device which increases an area of the protrusion portion displayed in an endoscope observation image when the press fitting fixing portion is attached to a distal end portion of a second endoscope insertion portion having a size different from that of a first endoscope insertion portion to which the press fitting fixing portion can be appropriately attached, and gives a warning about an inappropriate attachment state.
