Abstract:
A method for manufacturing a circuit component in which a conductive layer of a conductive material having a predetermined pattern is formed on the surface of an insulation substrate having a predetermined shape of an insulation material, the method comprising the steps of:forming the insulation substrate having a predetermine shape of the insulation material; forming the conductive layer of a conductive material on the entire surface of the insulation substrate formed into the predetermined shape by nonelectrolytic plating as a primary plating; integrally forming a resin mask of a material having the property of hydrolyzing in an alkali aqueous solution and resisting an acidic aqueous solution on the insulation substrate by forming the resin mask so that in the surface of the insulation substrate formed with the conductive layer, the part to which the conductive layer of the predetermined pattern is to be formed is exposed; overlaying a conductive layer by means of electrolytic plating with an acidic bath composition on the exposed part as a secondary plating; removing the resin mask by hydrolysis using an alkali aqueous solution; and removing the conductive layer of the primary plating by chemical etching, thereby forming the conductive layer of the predetermined pattern on the insulation substrate.
