PROBLEM TO BE SOLVED: To provide a data transmission method by which unnecessary radiation is reduced. SOLUTION: The transmission method for transmitting fast serial data from a first substrate 1 to a second substrate 4 through a harness 3, includes an S/P conversion step where the fast serial data is converted to slow parallel data by the first substrate 1, a step where the parallel data is transmitted through the harness 3, and a P/S conversion step where the transmitted parallel data is converted to fast serial data by the second substrate 4. Unnecessary radiation is reduced because the transmission frequency in the harness 3 is reduced.
