PROBLEM TO BE SOLVED: To provide a three-dimensional mounting board achieving impedance matching even when Z-direction wiring resultantly becoming inductive wiring exists.SOLUTION: A second printed wiring board 2 is arranged to be laminated through a space in the board thickness direction of a first printed wiring board 1. A Z-direction wiring part 3 is arranged in the board thickness direction through a space between the first printed wiring board 1 and the second printed wiring board 2 to connect the first printed wiring board 1 to the second printed wiring board 2. End opening stubs 91, 92 each made to be capacitive are arranged in connection parts between the Z-direction wiring part 3, and the first printed wiring board 1 and the second printed wiring board 2. |
