PROBLEM TO BE SOLVED: To provide a received frequency scanning device that is effective, even for a radio wave format such as SSB(single sideband) and a CW(continuous wave), where demodulation is difficult due to received frequency deviation. SOLUTION: This received frequency scanning device is provided with a 1st scanning control part 10-1 for making a 1st scanning frequency range designated by a 1st scanning frequency range designating means 2 to be scanned at a 1st scanning speed, and a 2nd scanning control part 10-2 for making a 2nd scanning frequency range to be scanned with the frequency of the width set by a scanning frequency width setting means 6, which includes a frequency indicated by a 2nd scanning center frequency indicating means 5a, as a target received frequency within the 1st scanning frequency range as the 2nd scanning frequency range at a 2nd scanning speed that is slower than the 1st scanning speed. For this reason, reception is enabled, even if target receiving frequency is shifted.
