PROBLEM TO BE SOLVED: To efficiently increase an available radio frequency.SOLUTION: A radio frequency management apparatus includes: a determination index value generation part 4 which generates a determination index value for extracting a candidate of a radio frequency to be deleted from an unavailable frequency list for each radio frequency and for each generation algorithm of the determination index value; an unavailable registration deletion candidate extraction part 5 which extracts a radio frequency of which the determination index value meets an extraction condition, as an unavailable registration deletion candidate from among radio frequencies in an unavailable state; a radio frequency availability determination part 6 that determines whether the candidate is available; a radio frequency availability determination result history storage part 9 that stores the determination index value, identification information indicating the generation algorithm of the determination index value, a determination result of the availability of the candidate and a date of obtaining the determination result as history information; and a radio frequency availability determination result display part 10 that displays the determination result of the availability of the candidate and the determination index value for each generation algorithm of the determination index value. |
