Abstract:
1. A printed wiring board comprising: an interlaminar insulating layer; a conductive layer formed on the interlaminar insulating layer and having a conductive pattern formed on the interlaminar insulating layer; and a capacitor positioned in the interlaminar insulating layer and comprising a dielectric body having a first surface and a second surface, a first electrode provided on the first surface of the dielectric body, and a second electrode provided on the second surface of the dielectric body, wherein the first electrode has an area facing and being smaller than the first surface of the dielectric body, the second electrode has an area facing and being larger than the second surface of the dielectric body such that the second electrode has an outer periphery portion protruding from an outer periphery portion of the dielectric body, the interlaminar insulating layer has a first opening extending to the first electrode of the capacitor and a second opening extending to the outer periphery portion of the second electrode of the capacitor, and the conductive layer has a first conductive portion formed in the first opening and connecting the first electrode to the conductive pattern and a second conductive portion formed in the second opening and connecting the second electrode to the conductive pattern.
