PROBLEM TO BE SOLVED: To provide a hybrid high frequency component that can reduce the number of switching components, can be used for an information terminal or the like and attain downsizing, power saving and simplicity of the circuit. SOLUTION: The hybrid high frequency component is used to transmit/receive 1st and 2nd signals in a different frequency band and includes a reception section that is provided with an antenna, a 1st reception port R×1 receiving the 1st signal, a 2nd reception port R×2 receiving the 2nd signal, and a diplexer that is connected to each reception port to distribute the 1st and 2nd signals, includes a transmission section that is provided with a 1st transmission port T×1 transmitting the 1st signal, a 2nd transmission port T×2 transmitting the 2nd signal, and a diplexer that is connected each transmission port and couples the 1st and 2nd signals, and includes a switch that switches selectively the connection of the diplexer of the transmission section or the reception section to the antenna.
