PROBLEM TO BE SOLVED: To provide a wiring board of which the high frequency property is improved.SOLUTION: A wiring board 10 includes a coplanar line including: a substrate 1 formed from a dielectric; a line conductor 2 formed on a surface; and ground conductors 3 which are disposed at both sides of the line conductor 2 while being spaced. The coplanar line includes a curve part R which is bent on a curved line, and is formed while making an interval between the line conductor 2 and the ground conductor 3 wide at an opposite direction side to a curving direction of the curve part R, and making the interval between the line conductor 2 and the ground conductor 3 narrow at the same direction side as the curving direction of the curve part R. Thus, the high frequency property such as a reflection property of the coplanar line can be improved. |
