PROBLEM TO BE SOLVED: To provide a distance measuring apparatus using an optical cutting method in which the whole image of a measuring object can be measured in a short time without giving a feature to slit light. SOLUTION: In the distance measuring apparatus, the reflected light of the slit light emitted by the measuring object itself is imaged, and a distance up to the measuring object is measured on the basis of the positional relationship between the light emitting position of the slit light and an imaging position. The apparatus is provided with a slit-light emitting means by which a plurality of beams of slit light are emitted simultaneously, a first imaging means which is arranged in a position at a short distance from the light emitting means and which images the reflected light of the slit light at the measuring object, a second image imaging means which is arranged in a position at a long distance from the light emitting means and which images the reflected light of the slit light at the measuring object, a distance estimation means which estimates the distance up to the measuring object on the basis of an image obtained by the first image imaging means and a distance determination means which determines the estimated distance on the basis of the output result of the distance estimation means and on the basis of an image obtained by the second image imaging means.
