ント配線板。 In a printed wiring board having a wiring pattern of two or more high-frequency signals or digital signals that interfere with and disturb each other separated in direct current or alternating current, the signal wiring patterns are connected approximately parallel to each other in close proximity to both sides or one side of the signal wiring pattern. A printed wiring board characterized in that a ground wiring pattern connected to the ground is provided with a length that is approximately the same as a portion adjacent to the signal wiring pattern.
