A method of manufacturing a multi-core ferrule, in which method a plurality of flat-surface metal sheets (2) containing a plurality of apertures (1) of the same size are laminated and fixed together. The plurality of apertures (1) before subjected to lamination and fixing are designed to be in positions and to have diameters such that they communicate with one another to be capable of forming a cavity, whereby the resulting ferrule is highly accurate in diameter and positions of the pores and is applicable to multi-core connectors, devices and so on. |
