To provide a ceramic composite and a production method therefor allowing ease of processing to be improved and fracture toughness to be improved simultaneously. The invention includes the steps of: preparing at least a liquid-form resin and a ceramic sintered body which has been sintered at a temperature which is 700&#xb0; C. to 100&#xb0; C. less than a sintering temperature at which a theoretical density is obtained; immersing the ceramic sintered body in the liquid-form resin, causing the liquid-form resin to infiltrate the ceramic sintered body; and hardening the infiltrated liquid-form resin to obtain a ceramic composite having a relative density of between 40% and 90% by causing the resin to infiltrate. Gaps where no resin has infiltrated are formed in the ceramic composite.

Ceramic composite and production method for ceramic composite

A sleeve for optical communication and method for manufacture for 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 cost. The invention is made by press-molding ceramic feedstock, which after cold isostatic pressing and sintering are performed thereto, and is made so that an inner circumferential surface, of a through-hole for inserting a ferrule formed on the length-direction of the axis, has a sintered state.
