Abstract
A circuit board and an electronic apparatus using the same are provided. The circuit board includes an integrated-circuit (IC) device arrangement region and an electronic device arrangement region. The circuit board includes a first external wiring layer and an inner wiring layer. The first external wiring layer includes a plurality of first signal traces and a ground extending portion that extend from the IC device arrangement region to the electronic device arrangement region. The inner wiring layer includes a ground portion and an inner signal trace. The ground portion defines an opening region, and the inner signal trace is located in the opening region and extends from a position under the IC device arrangement region to another position under the electronic device region. The ground extending portion and the opening region overlap with each other in a thickness direction of the circuit board.
