摘要：PURPOSE:To prevent reliably the overflow of a resin from a blind through hole in a substrate and to avoid reliably the generation of a void in internal layers in the substrate. CONSTITUTION:In a substrate 1, internal layer patterns and conductor parts on the sides of external layers are electrically connected to each other through a through hole. Soldering resists 6 are applied in the vicinity of at least the through hole on the sides of internal layers in the substrate 1. Adhesive sheets 7 are respectively stuck on the surfaces, which are respectively covered with the resists 6, of the internal layers. After this, flow type prepregs 8 are respectively laminated and pressed on the sides of the surfaces, which are respectively sticked with the sheets 7, of the internal layers.
