PROBLEM TO BE SOLVED: To secure a constant accuracy whether a measurement distance is large or small and speed up measurement. SOLUTION: A distance-measuring apparatus 1 which outputs object distance data by measuring a time from a projection time point to a reception time point of a pulse light has a plurality of light sources for projecting pulse lights of mutually different wavelengths, an optical member 13 for making optical axes of pulse lights projected from the plurality of light sources agree with each other, a light-splitting means for separating received pulse lights, and a plurality of photoelectric conversion devices corresponding one by one to the separated pulse lights. The plurality of light sources are made to emit and project light at the same time or sequentially with mutually different output intensities. The reception time point is detected on the basis of an output signal of a largest peak value in an appropriate range among output signals of the plurality of photoelectric conversion devices.
