Abstract

A first signal line is closer to a second ground conductor than a second signal line and, hence, crosstalk between the first and second signal lines is unlikely to be generated. By providing first opening portions in the second ground conductor, capacitive coupling between the first and second signal lines is reduced. Hence, in a transmission line including the first signal line, an increase in the capacitance due to the increased width of the first signal line is cancelled out by a decrease in the capacitance due to the increased distance from the first ground conductor and the first opening portions. Further, the width of the high-frequency transmission line need not be large. Further, since the capacitance is reduced by the first and second opening portions, the distances between the first ground conductor and the first and second signal lines are shortened.
