Endoscope cover and endoscope

An endoscope cover for attachment to a distal end of an insertion section of an endoscope, the cover comprising:

• a cover main body configured to be attached to the distal end of the insertion section, the cover main body comprising:
• an annular portion provided on a proximal side of the cover main body along the longitudinal axis of the insertion section and surrounding the distal end of the insertion section;
• a fragile portion provided at a position on the annular portion, the fragile portion forming a region in a longitudinal direction of the annular portion having a smaller cross-sectional area than adjacent regions of the annular portion in the longitudinal direction;
• and
• a buffer material provided on the cover main body, the buffer material including an end portion, the end portion extending distally to at least a same position as a distal end position of the fragile portion along the longitudinal axis, the end portion of the material being configured to reduce a force exerted from a distal side of the fragile portion onto the fragile portion along the longitudinal direction.
