To provide a wireless communication device with DFS function that can shorten a period during which wireless communication is not performed as much as possible.SOLUTION: A wireless device 10 (wireless communication device) includes: a communication unit 11 that transmits a first signal using a first channel, monitors a radar wave of the same frequency as the first channel, and stops transmitting the first signal using the first channel when the radar wave is detected; and a communication unit 12 that transmits a second signal using a second channel in parallel with wireless communication by the communication unit 11, monitors a radar wave of the same frequency as the second channel, and stops transmitting the second signal using the second channel when the radar wave is detected. When the communication unit 11 stops transmitting the first signal, the communication unit 12 transmits the first signal using the second channel.SELECTED DRAWING: Figure 2 【課題】無線通信が行われない期間を可及的に短くすることができる、ＤＦＳ機能を備えた無線通信装置を提供する。【解決手段】無線装置１０（無線通信装置）は、第１のチャンネルを用いて第１の信号の送信を行うと共に、当該第１のチャンネルと同じ周波数のレーダー波の監視を行い、当該レーダー波が検出された場合には第１のチャンネルを用いた第１の信号の送信を停止する通信部１１と、通信部１１による無線通信と併行して、第２のチャンネルを用いて第２の信号の送信を行うと共に、当該第２のチャンネルと同じ周波数のレーダー波の監視を行い、当該レーダー波が検出された場合には第２のチャンネルを用いた第２の信号の送信を停止する通信部１２と、を備え、通信部１１が第１の信号の送信を停止した場合、通信部１２は、第２のチャンネルを用いて第１の信号の送信を行う。【選択図】図２
