The present invention has the object of providing an overshoot/undershoot prevention device and overshoot/undershoot prevention method that are highly effective against both overshoot and undershoot. The overshoot/undershoot prevention device is provided with an overshoot shaping device that selects the portion of a waveform signal that equals or exceeds an overshoot determining potential when the potential of the waveform signal equals or exceeds the overshoot determining potential, outputs the selected portion as an overshoot waveform, attenuates the overshoot component of the waveform signal, and outputs the result as a shaped waveform in accordance with the time that the overshoot waveform continues. Also included is an undershoot shaping device that selects the portion of the waveform signal that equals or falls below an undershoot determining potential when the potential of the waveform signal equals or falls below the undershoot determining potential, outputs the sleeted portion as an undershoot waveform, attenuates the undershoot component of the waveform signal, and outputs the result as a shaped waveform in accordance with the time that the undershoot waveform continues.
