PROBLEM TO BE SOLVED: To further uniformize characteristic impedance of a transmission line.SOLUTION: A printed wiring board 100 includes a transmission line 101 which transmits a signal. The transmission line 101 includes: a signal wiring pattern 151 disposed on a conductor layer 181; and a signal wiring pattern 152 disposed on a conductor layer 184. The transmission line 101 includes via conductors 106, 107 which are arranged adjacent to each other and connect the signal wiring pattern 151 with the signal wiring pattern 152. Further, the transmission line 101 includes: a signal wiring pattern 153 which is disposed in a conductor layer 182 and connects the via conductor 106 with the via conductor 107; and a signal wiring pattern 154 which is disposed in a conductor layer 183 and connects the via conductor 106 with the via conductor 107. |
