A film deposition device (1A) of a metal film includes: a solid electrolyte membrane (13) that allows metal ions to be contained; a positive electrode (11) made of a porous body; a power supply part (14) that applies a voltage between the positive electrode and a base material; and a contact pressurization part (20) that comes into contact with the positive electrode (11) and uniformly pressurizes a film deposition region of a surface of the base material by the solid electrolyte membrane (13) via the positive electrode (11). The positive electrode (11) made of the porous body is capable of transmitting a solution containing the metal ions such that the metal ions are supplied to the solid electrolyte membrane. The power supply part (14) applies a voltage between the positive electrode and the base material so that the metal film made of the metal is deposited.

A method of producing layered cores for magnetic circuit components such as inductors and transformers suitable for use in the microelectronics industry. A series of pillars are created on a carrier Layers of the magnetic core are plated onto the exposed surface of the pillars. After the desired number of core layers are plated, the plated layers are ground down to expose the pillars, leaving a series of magnetic cores between the pillars. The pillars can then be removed, leaving a series of magnetic cores. The pillars are created by either building up pillars, such as copper pillars, or by slitting plastic mediums, such as dry film or epoxy plastic, the roughness of the magnetic cores produced depends on the method of forming the pillars.

In a film forming method, in a state where a metal solution is sealed in a first accommodation chamber of a housing with a solid electrolyte membrane and a fluid is sealed in a second accommodation chamber of a placing table with a thin film, a substrate is placed on the placing table and the placing table and the housing are moved relative to each other to cause the substrate to be interposed between the solid electrolyte membrane and the thin film, the solid electrolyte membrane and the thin film are pressed against the substrate interposed therebetween to cause the solid electrolyte membrane and the thin film to conform to a surface and a rear surface of the substrate, thereby forming a metal film.

A method for subjecting garment accessories to a surface electrolytic treatment provides various metallic colors to metallic garment accessories in a cost effective manner. The method can provide a first metallic color on one side of outer surface of the garment accessory and provide a second metallic color on the other side of the outer surface, by placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory.
