A distance-measuring apparatus is arranged to project light toward an object to be measured, receive reflected light from the measured object, and detect the distance to the measured object through arithmetic operation and integral operation. In the distance-measuring apparatus, a capacitance of an integrating capacitor 6 is set so as to discharge/charge the integrating capacitor 6 to the maximum when a time necessary for the first integral is minimum. In the detection of the distance to the measured object, when the time necessary for the first integral is longer than the minimum time, the first integral and second integral of the integrating capacitor are carried out repeatedly.
