    摘要: The present invention provides a mold for fine electroforming M having a simple structure. In order to improve the productivity of a metal product, an electrode portion can be arranged with a much higher density, and a metal thin film formed on the electrode portion can easily be peeled off. The present invention provides a manufacturing method for manufacturing the mold M with a higher accuracy and by an easier way.The mold for fine electroforming M has a conductive substrate 1 to function as a cathode during electroforming and insulation layer 2 having an opening 21, which has a shape corresponding to a shape of a plane shape of the metal product P and is through to the conductive substrate 1, and composed of an inorganic insulation material having a thickness T2 of not less than 10 nm and less than one-half the thickness T1 of the metal product P. The surface of the conductive substrate 1 exposed at the opening 21 is adapted to serve as the electrode portion.The manufacturing method of the mold M has steps of: forming an inorganic thin film 2′ to grow into the insulation layer 2 in an area excluding an area, where resist film R is pattern-formed, on the surface of the conductive substrate 1; and removing the resist film R to form the opening 21.

    摘要: A magnetic powder 4 is produced by use of a plating mold M which is pattern-formed with an electrode range 10 corresponding to the shape of a magnetic powder 4 and an insulative range surrounding the periphery of the electrode range, precipitating films 40 of the magnetic material selectively in the electrode range through an electroplating and then peeling the films 40 from the plating mold. The flat magnetic powders 4 where are regular in piano shapes and diameters among or between powders or where average crystal grain diameters are 100 nm or smaller, are much dispersed into an insulative resin as a bonding agent.
