Abstract:
1. A wiring pattern structure comprising: first and second electronic components arranged to send and receive differential signals, the first and second electronic components provided on a front surface of a board, and the first and second electronic components each having terminals; differential transmission paths each including a pair of first and second signal lines, each end of the first and second signal lines arranged at positions where corresponding terminals of the first and second electronic components are located so that the first and second electronic components are capable of being electrically connected to each other; and first and second electrostatic protection elements each having a first terminal and a second terminal, the first terminal of the first electrostatic protection element is connected to the first signal line and the first terminal of the second electrostatic protection element is connected to the second signal line; wherein the first and second electrostatic protection elements are disposed in an area between the first and second signal lines; and the first and second electrostatic protection elements are shifted in the width direction of the first and second electrostatic protection elements so as to partially overlap each other when viewed from the width direction.
