An example wireless communication device is provided with a binarizing circuit which precisely carries out binarization even if a level of an input signal is kept substantially consistent for a long period. The binarizing circuit includes: a comparator which outputs a data slicer output by comparing a generated signal generated from a demodulated signal with 0 level; a feedback circuit which detects a direct current level of the generated signal, thereby outputting an inversion signal of the direct current level; and an adder circuit which outputs the generated signal by adding the inversion signal to the demodulated signal. Since an offset canceller of the feedback circuit outputs 0 to an integration circuit when the generated signal falls within a predetermined range, the generated signal does not follow the demodulated signal even if the demodulated signal is kept at a substantially consistent level, thereby reducing errors.
