Abstract:
A multilayer printed wiring board includes a core substrate, a resin insulation layer laminated on the core substrate and a capacitor section coupled to the resin insulating layer. The capacitor section includes a first electrode including a first metal and configured to be charged by a negative charge, and a second electrode including a second metal and opposing the first electrode, the second electrode configured to be charged by a positive charge. A dielectric layer is interposed between the first electrode and second electrode, and an ionization tendency of the first metal is larger than and ionization tendency of the second metal.
