An endoloop having a screw coupled rear end portion according to the present invention has screw threads which are respectively engaged with each other at a coupled part between a hollow rod and a rear end portion such that the hollow rod and the rear end portion are coupled with or separable from each other by a screw coupling method whereby the rear end portion can be separated from the hollow rod even without applying strong force and thus a suture procedure using the endoloop can be carried out more easily.
