A distance measuring apparatus according to the present invention determines the distance to an object of range finding based on the amount of parallax between multiple images. The distance measuring apparatus includes: a number of simple lenses L1, L2 in substantially the same shape, on which light that has come from the object of range finding is incident; and an image capturing section N, which has a number of image capturing areas N1, N2 and which captures the images of the object of range finding that have been produced by the respective simple lenses L1, L2 on their associated image capturing areas N1, N2. The lens surfaces r1, r2 of each lens that are opposed to the object of range finding and the image capturing section, respectively, are only aspheric refracting surfaces. In each of the simple lenses L1, L2, the paraxial radii of curvature R1 and R2 of the lens surfaces r1, r2 that are opposed to the object of range finding and the image capturing section, respectively, and its focus length f satisfy the condition −2.4≦̸f(1/R1+1/R2)≦̸−0.6.
