A composite high-frequency component includes a transmission/reception selection switch. The transmission/reception selection switch includes a first diode disposed in series with a transmission signal line, a second diode disposed in shunt with a reception signal line. A first current route in which a direct current flows through the first diode and a second current route in which a direct current flows through the second diode are connected in parallel with each other. When a predetermined positive voltage is applied to a control terminal, a direct current flows through, in sequence, the control terminal, a resistor, an inductor, the diode, a strip line, a strip line, and a shared inductor, and a direct current also flows through, in sequence, the control terminal, the resistor), the diode, a strip line, the strip line, the strip line, and the shared inductor.
