Abstract
PURPOSE:To obtain a multilayer printed wiring board with low dielectric constant by using a specified resin for an inner layer. CONSTITUTION:An inner layer 1, a prepreg 2 and an outer layer 3 are prelimi narily made. As the inner layer 1, the material in which the circuits becoming inner layer circuits are formed on both surfaces of the laminated sheet of ethyl ene tetrafluoride resin, is used. In the multilayer printed wiring board, since ethylene tetrafluoride resin is used for the resin constituting the inner layer 1, while the dielectric constant of the multilayer printed wiring board may be lowered, the thermal deformation of the inner layer is prevented in forming the multilayers, and its dimension change may be minimized.
