A distance measurement apparatus for measuring distance to the target by measuring a time elapsed from the emission of pulsed light to the target until the receiving thereof. This apparatus comprising a light-emitting section, a light-receiving section, a delay circuit for delaying at least one of generation of the trigger signal with respect to a measurement start signal and the outputting of the measurement stop signal with respect to the reflected pulsed light and outputting thus delayed signal, a reference clock section, time measuring sections consisting of a start-side and stop-side fractional time signal measurement sections and a counter section, and a distance measurement section for determining, based thus measured items, the distance to the target according to the time from the emission of the pulsed light to the receiving thereof.
