Abstract
Since a width of an edge portion of a signal line of a first high frequency transmission line is changed with respect to a width of another portion thereof, a deviation of impedances in a connection portion of the first and second high frequency transmission lines can be suppressed, so that signal reflections occurred in the connection portion can be lowered and a signal passing characteristic is improved.
