Abstract:
To provide a process for producing a wiring substrate with conduction failure in a hole formed in an electrical insulator layer suppressed even without conducting an etching treatment using metal sodium, and with unexpected deformation such as warpage suppressed even when the electrical insulator layer contains no woven fabric or non-woven fabric comprising reinforcing fibers. A process for producing a wiring substrate  1 , which comprises forming a hole  20  in a laminate comprising a first conductor layer  12 , an electrical insulator layer  10  which contains a specific fluororesin layer (A)  16  and a heat resistant resin layer (B)  18 , contains no reinforcing fiber to substrate, and has a dielectric constant of from 2.0 to 3.5 and a linear expansion coefficient of from 0 to 35 ppm/° C., and a second conductor layer  14 , applying, to an inner wall surface  20 a  of the hole  20 , either one or both of a treatment with a permanganic acid solution and a plasma treatment without conducting an etching treatment using metal sodium, and then forming a plating layer  22  on the inner wall surface  20 a  of the hole  20.

Claim (Index 11):
The wiring substrate according to  claim 10 , wherein the electrical insulator layer has a layer structure of heat resistant resin layer (B)/fluororesin layer (A), a layer structure of heat resistant resin layer (B)/fluororesin layer (A)/heat resistant resin layer (B) or a layer structure of fluororesin layer (A)/heat resistant resin layer (B)/fluororesin layer (A).
