Abstract
A transmission device has a light emitting element for converting an electric signal to an optical signal and transmitting the same, and a drive section for outputting the optical signal from the light emitting element and driving the light emitting element by providing the electric signal to the light emitting element. The electric signal provided by the drive section to the light emitting element is a waveform deformed signal having a waveform in which a time required for a fall is longer than a time required for a rise in a binary signal having a signal of high level and a signal of low level.
