Claim:
An endoscope comprising: an attachment section having at least first and second sections extending in an axial direction from a rear end of said attachment section, wherein said attachment section is in the form of a pipe; a tubular curved section protective sheath having an end that covers an outer periphery of said first section, which extends from said rear end of said attachment section, so as to cover an endoscope curved section while leaving an outer periphery of said second section uncovered; a filamentous member wound around the outer periphery of said end of said tubular curved section protective sheath thereby affixing said end of said tubular curved section protective sheath to said first section of said attachment section; an adhesive agent layered on the outer periphery of at least said end of said tubular curved section protective sheath so as to cover said filamentous member; and a ring member fitted to the outer periphery of said end of said tubular curved section protective sheath so as to cover said adhesive agent, and an inner peripheral surface of said ring member being bonded to said filamentous member with said adhesive agent, wherein said ring member includes a small-diameter ring section having an inner diameter and a large-diameter ring section having an inner diameter, wherein said inner diameter of said large-diameter ring section is larger than said inner diameter of said small-diameter ring section, said large-diameter ring section is arranged surrounding said end of said tubular curved section protective sheath so as to cover said filamentous member, and said small-diameter ring section covers said second section and is directly bonded to said second section through said adhesive agent.
