Abstract
A mask for partial plating capable of performing partial electroplating selectively on a prescribed portion on a surface of an electrically isolated metal member provided on an insulated board is provided. Methods for producing an insulated circuit board and using the mask for partial plating are also provided. The mask for partial plating includes an insulated sheet member having an opening corresponding to the portion to be plated, and a structure including a partial region on one surface in the thickness direction of the insulated sheet member being coated with one or plural conductive sheet members attached to the region. The conductive sheet member is adhered to the surface of the insulated sheet member, for example, with an adhesive or an adhesive member. The conductive sheet member may be engaged in a recessed portion formed on the surface of the insulated sheet member.
