PROBLEM TO BE SOLVED: To provide a waveform width adjusting circuit which does not shorten the waveform width of a signal whose waveform width is equal to or less than a limit. SOLUTION: A delay circuit (5) having a predetermined delay time is installed in a signal propagation path, and the circuit (6) is provided which makes adjustments so as to output a signal having a waveform width shortened from an output terminal when the waveform width from one of rise transition to fall transition of a signal of an input terminal (1) to the other one is larger than the delay time of the delay circuit (5) and output the signal with the original waveform width without shortening the waveform width when the waveform width of the signal of the input terminal (1) is equal to or less than the delay time, so that the waveform width of the signal whose waveform width is equal to or less than the limit is not shortened.
