To provide a receiving sound eliminating circuit by which noise at the time of noise elimination can more naturally be heard.

A sound codec (decoder part) 5 decodes a receiving sound data signal received/demodulated by a reception circuit part 2 and transmits PCM data to a D/A converter 6. When receiving sound is eliminated, the latest background noise data signal selected by a background noise data selection means 9 and is stored in a background noise data storage means 10 is sent to sound codec (decoder part) 5 and the data signal is decoded instead of the received/ demodulated receiving sound data signal. Thus, sound similar to that which is heard when a land side is silent is outputted. Consequently, unnatural feeling when receiving sound is eliminated can be reduced.
