The transmission device calculates a DC balance value of input data, compares the DC balance value and a cumulative value thereof, and compares the sign of the DC balance value and the sign of the cumulative value.

When the signs are different signs, the transmission device performs a process of setting the input data as the intermediate data and transmits the intermediate data by a serial signal.
