A high-frequency module includes an antenna, an impedance matching circuit, and a transmission wire. The transmission wire is connected between the antenna and the impedance matching circuit. The transmission wire includes a dielectric layer, a signal layer, and two ground layers. The signal layer and the ground layers are located on the dielectric layer. The ground layers are located at opposite sides of the signal layer respectively. A space is formed between a signal and each ground layer.
