Provided is an output apparatus that outputs an output signal corresponding to an input signal, comprising a plurality of drivers that each output an intermediate signal having a waveform corresponding to the input signal; an adding section that adds together the intermediate signals output from the drivers and outputs the result as the output signal; and a control section that controls a difference in delay amount, which is from when the input signal begins to change to when the intermediate signal begins to change, among the drivers according to a designated slew rate.
