    Abstract: A structure of a multilayer printed wiring board having a wiring lead-out port can be easily formed. A large number of products can be easily manufactured with good size reproducibility. A method of manufacturing the same is also are disclosed. The multilayer printed wiring board is characterized by having a signal circuit conductor perfectly covered by an earth circuit in its inside and a wiring lead-out port. A signal circuit conductor having a branch pattern is preferable. The multilayer printed wiring board is manufactured by selectively etching the copper of a cladding sheet manufactured by bonding a copper foil to a nickel foil with 0.1-3% reduction and forming a signal circuit conductor perfectly covered by an earth circuit and the wiring lead-out port.
