Provided are a receptacle attached with an optical isolator and a manufacturing method thereof, capable of easily performing position alignment among an end surface of a magnet, an end surface of a fiber stub, and a polarization plane of a polarizer and dimension calculating of the optical isolator without an increase in the number of parts. The optical isolator is constructed by fitting a fiber stub into which an optical fiber is inserted and of which end surface is formed to be slanted with a predetermined angle into a ferrule holder, by forming an end surface of the magnet to be slanted with the same angle as the predetermined angle, and by fixing the optical isolator element to the magnet. The receptacle attached with an optical isolator is constructed by integrally fixing the optical isolator to the end surface of the fiber stub by fitting the optical isolator into an inner diameter portion of the ferrule holder.
