Abstract:
1. The multilayer printed wiring board, comprising: a core substrate comprising a resin; a resin insulation layer laminated on the core substrate; and a capacitor section coupled to the resin insulating layer, the capacitor section comprising: a dielectric layer interposed between the first electrode and second electrode, wherein the dielectric layer is made from ceramic and an ionization tendency of the first metal is larger than an ionization tendency of the second metal wherein the dielectric layer comprises: a sputter film formed by sputtering directly on an inner surface of the first-electrode; and a sol-gel film formed by a sol-gel method directly on the sputter film such that the sol-gel film faces an inner surface of the second-electrode which opposes the inner surface of the first electrode.
