A capsule endoscope (2) which functions as a transmitting apparatus includes an in-vivo information obtaining unit (21) that obtains in-vivo information, a signal processing unit (22) that generates and outputs a main information component based on the obtained in-vivo information, a dummy component output unit (23) that generates and outputs a dummy component containing an alternating-current signal having a predetermined frequency at a timing corresponding to a gap portion between the main information components, an adding unit (24) that combines the main information component and the dummy component, and a radio transmitting unit (25) that transmits a signal obtained as a result of combining by the adding unit (24), in order to realize a transmitting apparatus that alleviates inconveniences incurred by a presence of gap portions in a radio signal transmitted. Since the dummy component is inserted in the gap portion between the main information portions, the frequency band of the transmitted radio signals is made narrower, and the fluctuation of the average level of the radio signals is suppressed.
