Communication device, method for controlling communication device, and recording medium

The invention provides a communication device, a control method of the communication device, and a recording medium, which can reduce the processing load of a server device (3). A communication device (21) is provided to a moving body (2), and is provided with: a recording unit (305) that records data (8) in which a state value indicating the state of the moving body (2) is recorded; a recording data control unit (303) that controls the recording by the recording unit (305); and a transmission unit (302) that transmits the data (8) recorded by the recording unit (305) to a server device (3), the recorded data control unit (303) causes the recording unit (305) to record first data, which is the data (8) in which the state value has changed to a specific value, after the mobile body (2) has started, and transmits the first data to the server device (3) after the first data has been recorded. The recorded data control unit (303) restricts the recording unit (305) from recording the first data again until a prede
