To provide a phase modulation type receiver capable of reducing power consumption to a minimum.

The present invention relates to the phase modulation type signal receiving device 10 comprising an RF signal processing unit 100 for receiving a transmitted signal modulated by a predetermined modulation system (phase modulation system) and down-converting the received signal, and a baseband signal processing section 200 for demodulating digital data on the basis of a state of modulation, for each symbol term, of the signal down-converted by the RF signal processing section 100, wherein a control section 230 which controls so as to intermittently operate the RF signal processing section 100 only during a predetermined partial period in each symbol term of the phase modulated signal, is included.
