Abstract An endoscope cover comprising a cylindrical rigid cover composed of an elastic material, which is fitted to an endoscope to cover a top end rigid portion of the endoscope. A transparent window arranged on a closed face formed on the top end of the rigid cover to confront at least an observation port and an illuminating port, which are arranged on the top end of the endoscope, and a bag-shaped covering member having a length covering at least an intermediate conduit portion of the endoscope, which is attached to the rear part of the endoscope. A groove or notched face is formed in the longitudinal direction of the outer periphery of the top end rigid portion of the endoscope and an anchoring groove is formed on the circumferential face portion. Anchoring projections are formed at confronting positions on the inner circumferential face of the rigid cover and are fitted in the anchoring groove formed in the top end rigid portion to fix the rigid cover to the top end rigid portion and cover the intermediate conduit portion with the covering member.
