Abstract:
1. A production method for a fine metal component, characterized by comprising the steps of: fixing a mold composed of an insulating material having a fine through-hole pattern corresponding to the shape of a fine metal component on a conductive substrate with a conductive film composed of a conductive paste, characterized in that a metal powder having the form of a lot of fine metal particles including a metal selected from the group consisting of Ni, Fe, Co, and alloys of not less than two of Ni, Fe, and Co being linked in a chain shape by magnetism is contained as a conductive component, intervened between the conductive substrate and the mold to form a mold for electroforming; and making a plated coating selectively grow on a surface of the conductive substrate or the conductive film exposed at a portion of the through-hole pattern of the mold for electroforming by electroplating using the surface as an electrode, to form a fine metal product corresponding to the shape of the through-hole pattern.
