Provided are a sleeve for optical communication and a method for manufacturing the sleeve for optical communication, for which withdrawal force for ferrules, which are generally used in the technical field of optical communication, or connection loss between ferrules is a predetermined value, and for which manufacturing steps are reduced so as to allow reduction of manufacturing costs. The sleeve for optical communication is made by press-molding ceramic feedstock, after which cold isostatic pressing and sintering are performed thereto, and is made so that an inner circumferential surface (4a), of a through-hole (2a) for inserting a ferrule formed on the length-direction of the axis, has a sintered state.
