1. A wiring board for a semiconductor integrated circuit package, comprising:
a plurality of metal layers including a ground plane, a power supply plane, and a signal wiring layer which are stacked;
a surface layer in which an electronic device mount part is surrounded by an electrode plane, wherein the electronic device mount part has device connecting pads arranged in an area-array form;
ground pads and power supply pads arranged on an inner side of the electronic device mount part; and
connecting wiring for connecting between the electrode plane and one of the connecting pads having a same potential as the electrode plane wherein the electrode plane, the one of the connecting pads, and the connecting wiring are disposed on a same layer.
