To provide a wireless communication apparatus capable of automatically selecting an optimum wireless communication means depending on the pressure of interference of a radio wave during transmission so as to make efficient transmission even when a plurality of wireless communication means are intermingled and in use at the same frequency band.

The wireless communication apparatus 10 includes: an IEEE802.11b wireless section 4 and an IEEE802.11b base band section 5 in charge of a wireless LAN in compliance with the IEEE802.11b; and an IEEE802.11b wireless section 4 and an IEEE802.11b base band section 5 in charge of wireless communication in compliance with the Bluetooth, which use the same frequency band, and a control section 6 periodically monitors the presence of radio wave interference according to the IEEE802.11b and selects the Bluetooth from the wireless LAN when detecting radio wave interference to conduct communication. When no radio wave interference is detected, the communication in compliance with the IEEE802.11b is continued.
