Abstract: Provided is an endoscope that can fix a guidewire and stably hold a treatment tool. The endoscope includes a distal end body (36) having an elevator housing (62) that opens toward a first direction, a treatment tool lead-out port (80) that opens inside of the elevator housing (62), and an elevator (60) that is provided inside of the elevator housing (62) so as to be rotatable between an elevated position and a lowered position, the elevator (60) having a treatment tool guiding surface (60a). A facing wall portion (66), which is on a proximal end side and an opening part of the elevator housing (62), has a concave surface (96) that is formed on an inner side of the elevator housing (62) and a convex surface (94) that is formed at a position closer than the concave surface (96) to an opening. When the elevator (60) is in a forward position that is on the lowered position side relative to the elevated position, the concave surface (96) and the treatment tool guiding surface (60a) constitute a treatment tool holding portion (99) for holding a treatment tool, and, when the elevator (60) is in the elevated position, the convex surface (94) and the treatment tool guiding surface (60a) constitute a guidewire fixing portion (98) for fixing a guidewire.

Abstract: There is provided an endoscope capable of suppressing the degradation of a distal-end-part body over time that is caused by the sandwiching of a treatment tool.An endoscope includes a distal-end-part body that is provided at a distal end of an insertion unit. The distal-end-part body includes an elevator-housing space-forming wall that forms an elevator-housing space opened in a direction perpendicular to the direction of the longitudinal axis of the insertion unit, a lead-out portion that includes a treatment tool outlet opened into the elevator-housing space, and an elevator that is provided in the elevator-housing space so as to be rotatable about a rotating shaft between a standing position and a fallen position and includes a guide surface guiding a treatment tool. The elevator-housing space-forming wall includes an opening wall portion provided on an opening side of the elevator-housing space. An opposite wall portion, which is opposite to the guide surface in a case where the elevator is in the standing position, of the opening wall portion is made of a material harder than the other wall portion other than the opposite wall portion.
