PROBLEM TO BE SOLVED: To provide a reception device which rapidly searches an optimum value of a control signal, and corrects deviation of a tuning frequency of an antenna caused by influence of an object adjacent to the reception device. SOLUTION: The amount and direction of change of the tuning frequency of an antenna 101 changed by an object adjacent to the antenna 101 are specified; when searching for an optimum value of a control signal from an arithmetic part 104, the range of the value of the control signal to be searched for is limited in advance; and the deviation of the tuning frequency of the antenna 101 is corrected by a tuning frequency adjustment part 102 by rapidly executing the search.
