PROBLEM TO BE SOLVED: To provide a wireless LAN device capable of precisely determining an unnecessary signal. SOLUTION: The wireless LAN device includes: a reception signal intensity detector 108 which detects the intensity of a reception signal; a reception signal intensity threshold setting part 115 which dynamically changes a threshold; a reception signal intensity threshold determination part 114 which determines whether the intensity detected by the reception signal intensity detector 108 is equal to or lower than the threshold set by the reception signal intensity threshold setting part 115; a training signal correlation operation and determination part 116 which operates an autocorrelation value of a training signal included in the reception signal and determines whether the operated autocorrelation value is equal to or lower than a threshold set by a training signal correlation threshold setting part 117 or not; and a base band signal processing part 118 which determines whether the reception signal should be rejected or not on the basis of a determination result of the reception signal intensity threshold determination part 114 and that of the training signal correlation operation and determination part 116.
