ABSTRACT:
A wiring pattern structure having differential transmission paths electrically connects an integrated circuit element and a connector, which are arranged on a printed wiring board. Each of the differential transmission paths includes a pair of first and second signal lines. The first and second signal lines are substantially hook-shaped and a substantially rectangular area is formed between the first and second signal lines. First and second electrostatic protection elements are disposed in the substantially rectangular area. A bent portion of each of the first and second signal lines may be rounded.
