A wireless device capable of reliably detecting a tone squelch signal in a short time is provided. The wireless device which detects a tone squelch signal contained in received baseband signals is provided with: a frequency shifting unit (quadrature demodulation unit (503)) which shifts the received baseband signal in the negative frequency direction by a preset frequency of a tone squelch signal; LPF (504-1, 504-2) for eliminating unnecessary frequency components from the output of the frequency shifting unit; and an assessment unit (510) which assesses presence/non-presence of the tone squelch signal on the basis of the output from the LPF (504-1,504-2).
