MULTILAYER PRINTED SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a multilayer printed substrate on which an inductor formed of wiring is arranged effectively so as not to deteriorate transmission quality.

SOLUTION: The multilayer printed substrate is provided with the inductor formed thereon. In this case, the inductor comprises coil wiring and a first via hole separated from the coil wiring, and a metal film is formed on the inner wall thereof, so that an induced current is made to flow through the metal film by a high-frequency current which flows through the coil wiring.
