Abstract:
1. A method for manufacturing a multilayer printed wiring board, comprising: providing a core substrate; laminating a resin insulation layer on the core substrate; forming a capacitor section including a high- forming an outermost insulating layer over the capacitor section; forming a ground pad on the outermost insulating layer and electrically connected to the first electrode; and forming a power source pad on the outermost insulating layer and electrically connected to the second electrode, wherein said forming a capacitor section includes selecting the first metal for forming a ground electrode of the capacitor section, selecting the second metal for forming a power source electrode of the capacitor section, wherein the first and second metals are selected such that the second metal has a smaller ionization tendency than the ionization tendency of the first metal, providing said first electrode formed of the first metal, and providing said second electrode opposing the first electrode and formed of the second metal.
