PROBLEM TO BE SOLVED: To provide a radio communication apparatus which stably operates by reducing noise regarding the radio communication apparatus which performs data communication by radio. SOLUTION: The radio communication apparatus 1 is constituted so that it has an antenna 21 for transmitting/receiving a radio signal, a switch part 18 which switches a transmitting state for outputting a transmitting signal to the antenna 21 and a receiving state for inputting a receiving signal from the antenna 21, switching signal output wiring (9, 10) which output switching signals for switching the transmitting state and the receiving state to the switch part 18 and filter parts (37, 38, 39, 41) which attenuate the noise mixed in the switching signal output wiring.
