A wireless communication device includes: a transmission/reception unit (11) for performing wireless communication including carrier sensing; a counting unit (121) for counting number of executions of carrier sensing and number of erroneous carrier sensing instances in carrier sense; and a determination unit (122) which determines that carrier sensing is not abnormal if a ratio of the number of erroneous carrier sensing instances to the number of executions of carrier sensing is less than a predetermined threshold value, and determines that carrier sensing is abnormal if the ratio is greater than or equal to the predetermined threshold value.
