A method of producing metal ferrules and an apparatus therefore enable metal ferrules to be produced with high productivity and high dimensional accuracy by arranging a plurality of long-sized core wires. A jig receives a metal to be electroformed and is placed in an electroforming tank, a holding unit in which a plurality of core wire holder for holding core wires are held in circumferential array is installed in the electroforming tank, and the core wire holders and the holding unit are rotatable on their respective axes. It is preferable that the resistivity of the core wires be 5&#xd7;10&#x3a9;cm or less. A core wire plated within a thin layer of metal having a resistivity of 5&#xd7;10&#x3a9;cm or less may be used. A conductive electric discharge body may be provided on the front end of the core wire.
