摘要

PURPOSE: A multilayered printed wiring board is provided to prevent the swell of the conductor layer and the deterioration of the adhesion between the insulating resin layer and the conductor caused by remaining solvent. CONSTITUTION: A multilayered printed wiring board is a lamination of the insulating resin layer and the conductor layer upon a sheet. The conductor layer composed at least of a signal layer and a power supply layer has a lattice-like conductor pattern of the power supply layer.
