Abstract: A multi-layer printed circuit board includes an embedded capacitor substrate composed of a power source conductor layer and a ground conductor layer, the layers being disposed close to each other. The power source conductor layer has a first power source plane to supply power to a circuit element, and a second power source plane that is separated from the first power source plane by a gap and functions as a main power source. The first power source plane is partially connected to the second power source plane by a connecting line. The ground conductor layer has an opening at a position overlapping with a projected image when the connecting line is projected on the ground conductor layer. This structure suppresses propagation of the noise caused at the circuit element and reduces radiation noise in the printed circuit board.

Abstract: An electrical connecting member is provided with a holding member made of an electric insulating material and a plurality of conductive members held by the holding member in a state of being insulated with each other. One end of each of the conductive members is exposed on one surface of the holding member and the other end of each of the conductive members is exposed on the other surface of the holding member. The conductive members have portions exposed from the holding member, the length of which is longer than the thickness of the holding member. These exposed portions are easily deformed by the pressure force exerted at the time of connecting electric circuit components to reduce the coupling load even when there is irregularity in the heights thereof or unevenness in the junctions of the objects connection, hence enabling high density connections between the electric circuit components. The exposed portions can also be formed to have empty holes, i.e.

The electroconductive members are mutually insulated from each other and one end of each of the electroconductive members is exposed at one surface of the holding member and the other end is exposed at another surface of the holding member. A holding member is formed by forming a layer on a base member with the holding member having a photosensitive resin on the uppermost surface of the layer. The holding member is exposed and developed by forming a plurality of holes through the holding member, thereby exposing the uppermost surface of the layer. A part of the exposed layer is etched away and the holes on the holding member are filled with an electroconductive member. The remaining layer and base member are then removed.
