Abstract
A single-sided circuit substrate for a multilayer printed writing board has an insulating hard substrate, a conductor circuit formed on a surface of the substrate, an adhesive layer formed on the other surface, and at least one viahole through the substrate and the adhesive layer so as to pass these layers and contact with the conductor. The viaholes are filled with conductive paste. The invention also provides a multilayer printed wiring board having an IVH structure constituted with single-sided circuit hard substrates and a method of efficiently manufacturing the same with high yield.
