         4 . The endoscope cap according to  claim 3 , wherein the cover is breakable by a user's bare hand while being attached to the distal end of the insertion part. 
     
     
         5 . The endoscope cap according to  claim 1 , wherein the window part has a concave polygon formed by a side parallel to the opening end and a side vertical to the opening end. 
     
     
         6 . The endoscope cap according to  claim 5 , wherein the cover is an injection-molded article. 
     
     
         7 . The endoscope cap according to  claim 5 , wherein the cover is breakable by a user's bare hand while being attached to the distal end of the insertion part. 
     
     
         8 . The endoscope cap according to  claim 1 , wherein the cover is detachable from the endoscope by breaking the cover through the cutout. 
     
     
         9 . The endoscope cap according to  claim 8 , wherein the window part has a concave polygon formed by a side parallel to the opening end and a side vertical to the opening end. 
     
     
         10 . The endoscope cap according to  claim 8 , wherein the cover is an injection-molded article. 
     
     
         11 . The endoscope cap according to  claim 8 , wherein the cover is breakable by a user's bare hand while being attached to the distal end of the insertion part. 
     
     
         12 . The endoscope cap according to  claim 1 , wherein the cutout has an edge contiguous to the edge of the window part and has a curved surface vertical to an outer surface of the cover. 
     
     
         13 . The endoscope cap according to  claim 12 , wherein the window part has a concave polygon formed by a side parallel to the opening end and a side vertical to the opening end. 
     
     
         14 . The endoscope cap according to  claim 12 , wherein the cover is an injection-molded article. 
     
     
         15 . The endoscope cap according to  claim 12 , wherein the cover is breakable by a user's bare hand while being attached to the distal end of the insertion part. 
     
     
         16 . The endoscope cap according to  claim 12 , wherein the cover is detachable from the endoscope by breaking the cover through the cutout. 
     
     
         17 . The endoscope cap according to  claim 16 , wherein the window part has a concave polygon formed by a side parallel to the opening end and a side vertical to the opening end. 
     
     
         18 . The endoscope cap according to  claim 16 , wherein the cover is an injection-molded article. 
     
     
         19 . The endoscope cap according to  claim 16 , wherein the cover is breakable by a user's bare hand while being attached to the distal end of the insertion part. 
     
     
         20 . A method of removing an endoscope cap, comprising:
 holding an insertion part of an endoscope having a distal end to which the endoscope cap including a cover having a bottomed cylindrical shape and a window part opened at a side surface is attached;   breaking the cover through a cutout provided at a single position of a part of an edge of the window part not extending along a longitudinal direction of the cover by a user's bare hand; and   removing the cover broken from the insertion part.
