PROBLEM TO BE SOLVED: To provide a radio communication device capable of precisely passing a component of a desired frequency band of a signal for transmission, while making the radio communication device used as an outdoor device, or the like, compact and lightweight. SOLUTION: The radio communication device comprises a spurious rejection filter 11 which removes the component of local oscillation frequency of a signal of a high-frequency band output from a transmission frequency converter 20, an amplification unit 12 which amplifies the signal passed through the spurious rejection filter 11 and has a matching circuit 14 for removing a component of a frequency band higher than the desired frequency band in signals before and after the amplification, and an antenna 40 which transmits the signal amplified by the amplification unit 12, the spurious rejection filter 11 and amplifying unit 12 being connected by a strip line 15 removing a component of a frequency band lower than the desired frequency band.
