Abstract
A printed wiring board in which control of a characteristic impedance of a signal transmission pattern is realized. The printed wiring board includes a flat plate base material, a signal transmission pattern provided on at least one surface of the base material for transmitting a high frequency signal, an insulator layer formed with a constant thickness to cover the signal transmission pattern, and a grounded control unit provided on the insulator layer opposing the signal transmission pattern for controlling a characteristic impedance of the signal transmission pattern.
