Provided are a substrate for a printed wiring board, and a printed wiring board, which are not limited in size because vacuum equipment is not necessary for the production, in which an organic adhesive is not used, and which can include a conductive layer (copper foil layer) having a sufficiently small thickness. Also provided are a method for producing the substrate for a printed wiring board, and a method for producing the printed wiring board. A substrate for a printed wiring board includes an insulating base, a first conductive layer that is stacked on the insulating base, and a second conductive layer that is stacked on the first conductive layer, in which the first conductive layer is a coating layer composed of a conductive ink containing metal particles, and the second conductive layer is a plating layer. |
