PROBLEM TO BE SOLVED: To provide a lens array for optical reading which is easily manufactured and which restrains influence of stray light. SOLUTION: The lens array for optical reading is constituted of a block-shaped lens array main body 10 where a plurality of lens elements 11 and 12 are arrayed in a line on upper and lower surfaces, and a frame member 20 surrounding the main body 10 and formed of light absorbing resin material. The frame member 20 is constituted of an external frame part 21 arranged on the circumference of the main body 10 and a partition part 24 projecting to the inner part of the main body 10 from the external frame part 21. The partition part 24 is equipped with an optical aperture 25 where a plurality of through-holes 25a and 25a fit to the array of the lens elements 11 and 12 are arrayed in a line.
