    Abstract: Provided is a multilayer printed board 10 having three single-sided conductor pattern films 16 each having a conductor pattern 13 formed on one surface of a resin film 12 having a through hole 11 and a filled through hole 15 that is the through hole 11 filled with a conductor 14 integrally with the conductor pattern 13. These single-sided conductor pattern films 16 are stacked in such a manner that their tops are oriented in the same way. The conductor patterns 13 of the single-sided conductor pattern films 16 are electrically connected via the filled through holes 15. As the conductor patterns 13 of the single-sided conductor pattern films 16 are interlayer connected via the filled through holes 15, the interlayer connection reliability can be enhanced.

    Abstract: The present invention provides a method for manufacturing metallized aluminum nitride substrate, the method comprising: Step A for forming a high-melting point metal layer over a sintered aluminum nitride substrate; Step B for forming over the high-melting point metal layer an intermediate metal layer of at least one selected from the group consisting of: nickel, copper, copper-silver, copper-tin, and gold by plate processing; and Step C for forming a surface metal layer containing silver as a main component over the intermediate metal layer by coating a silver paste whose glass component content is 1 mass % or less and firing under nonoxidizing atmosphere. By this method, it is capable of forming a glass component-free silver layer which is adhered at a high degree of adhesion strength onto the high-melting point metal layer formed over the aluminum nitride substrate as a top face by thick-film method using a silver paste which makes thick-membrane forming easier.
