A communication apparatus exhibiting improved certainty and stability in communication. In a wireless terminal ( 100 ) serving as the communication apparatus, a transmission possibility determining part ( 186 ) uses an AIFS and a backoff value to control the transmission timing of transport data, and an AIFS managing part ( 181 ) adjusts the AIFS value related to the transport data in accordance with an elapsed time from the occurrence of a transmission request of the transport data. In this way, the AIFS value related to any transport data having a long elapsed time from the occurrence of a transmission request of the transport data can be reduced, and a predetermined wait time determined by the AIFS and backoff values also can be reduced. Accordingly, the probability of the transport data being transmitted with a higher priority than the other ones can be raised, whereby the possibility of the transport data being abandoned because of a timeout can be reduced. As a result, the certainty and stability in communication can be improved.
