To provide a technique capable of dividing an input signal into two with low loss while restraining the up-sizing of a high frequency transmission line, in the high frequency transmission line for dividing the input signal into two.SOLUTION: A high frequency transmission line 1 includes a multilayer dielectric substrate 2, a first signal line 3, a connection conductor 4, two signal lines 5, 6, and a radiation suppression member 7. The multilayer dielectric substrate 2 includes an inner layer where a ground plane 20 is placed. The first signal line 3 is provided on the first surface of the multilayer dielectric substrate 2, and a signal is inputted. The connection conductor 4 has a first end for connection with one end of the first signal line 3. The two signal lines 5, 6 are provided on the second surface of the multilayer dielectric substrate 2, and have one ends for connection with the second end of the connection conductor 4. The radiation suppression member 7 is connected with the second end of the connection conductor 4, and restrains radiation of signals.SELECTED DRAWING: Figure 1 【課題】入力信号を２分配する高周波伝送線路において、当該高周波伝送線路の大型化を抑えつつ入力信号を低損失で２分配することが可能な技術を提供する。【解決手段】高周波伝送線路１は、多層誘電体基板２と、第１信号線路３と、接続導体４と、２つの第２信号線路５，６と、放射抑制部材７と、を備える。多層誘電体基板２は、グランドプレーン２０が配置された内層を含む。第１信号線路３は、多層誘電体基板２における第１の表面に設けられ、信号が入力される。接続導体４は、第１端が第１信号線路３の一端に接続される。２つの第２信号線路５，６は、多層誘電体基板２における第２の表面に設けられ、各々の一端が接続導体４の第２端に接続される。放射抑制部材７は、接続導体４の第２端に接続され、信号が放射されるのを抑制する。【選択図】図１
