There is provided a distance measuring device capable of improving the accuracy of measurement while reducing power consumption. A variation amplification part amplifies a variation in a temporal relative relationship between an electrical signal output from a light receiving element and a clock signal generated by a clock generation unit. Subsequently, a synchronizing part generates a synchronizing signal by synchronizing an electrical signal with a clock signal on the basis of the electrical signal and the clock signal after a variation is amplified by a variation amplification part. Subsequently, a histogram creating part creates a histogram based on a period of time from when a light source emits light to when the light receiving element receives reflected light, on the basis of the synchronizing signal generated by the synchronizing part. Subsequently, a distance calculation part calculates a distance to an object on the basis of the histogram created by the histogram creating part.
