PURPOSE: A data receiving device is provided to extract at least a partial band signal from a received phase-modulated signal, to obtain a detection signal through delay detection and to easily make in a simple structure as an LSI device without requiring a plurality of analog circuits. CONSTITUTION: A data receiving device(1) extracts at least one partial band signal from frequency components of a received phase-modulated signal, and then obtains a detection signal through delay detection. The data receiving device(1) includes a first sampler(100), a second sampler(101), a partial band extracting section(102), a first delay detection operating section(103), and a second delay detection operating section(104). The first sampler(100) and the second sampler(101) have connected prior thereto a frequency converter circuit(105).
