A radio broadcasting reception apparatus capable of receiving radio broadcasting and IP radio broadcasting having relationship of simultaneous broadcasting with the radio broadcasting, the radio broadcasting reception apparatus comprising: a radio receiver configured to receive the radio broadcasting; an IP radio player configured to receive the IP radio broadcasting; an output unit configured to output one of reception sound of the radio receiver and reception sound of the IP radio player; a delay unit configured to delay the reception sound of the radio receiver output by the output unit; an evaluation value calculator configured to calculate an evaluation value representing the quality tendency of reception quality up to the present; and a seamless switching controller configured to allow the IP radio player to start reception of the IP radio broadcasting having relationship of simultaneous broadcasting with the radio broadcasting that is outputting reception sound, allow the delay unit to delay (508, 514) the reception sound of the radio receiver output by the output unit by a delay time of the IP radio broadcasting with respect to the radio broadcasting, and allow the output unit to switch output reception sound from the reception sound of the radio receiver to the reception sound of the IP radio player when the evaluation value is less than a predetermined threshold value, during a period of time for which the output unit is outputting reception sound of the radio receiver, characterized in that the evaluation value calculator is configured to calculate the evaluation value by changing the evaluation value by a predetermined update amount in a direction close to a working reference value that is a reference value corresponding to a current reception quality range that is a range of reception quality including reception quality of the radio broadcasting of the radio receiver at a time point according to a predetermined correspondence relationship between the range of reception quality and a plurality of reference values, at each time point, and the predetermined correspondence relationship is a relationship in which a range of better reception quality corresponds to a larger reference value wherein, when the evaluation value is larger than the working reference value, the evaluation value calculator is configured to use, in the calculation of the evaluation value, an update amount determined such that the evaluation value decreases increasingly as a current reception quality range is a range of worse reception quality, and when the evaluation value is smaller than the working reference value, the evaluation value calculator is configured to use in the calculation of the evaluation value, an update amount determined such that the evaluation value increases increasingly as a current reception quality range is a range of better reception quality. a radio receiver configured to receive the radio broadcasting;
