A pulse stretching circuit having a pulse delay circuit for receiving an input pulse signal and for outputting a delay pulse signal, and a pulse adjustment circuit, connected to the pulse delay circuit, receiving the input pulse signal and the delay pulse signal and for outputting an output pulse signal having a pulse width longer than a pulse width of the input pulse signal. The pulse adjustment circuit causes a leading edge of the output pulse signal in response to a leading edge of the input pulse signal, keeps a state in which the output pulse signal is displaced with the leading edge thus caused longer than a total time of times for both pulse widths of the input pulse signal and the delay pulse signal, and causes a trailing edge of the output pulse signal in response to a trailing edge of the delay pulse signal.
