SOLUTION: A lens array unit includes a first lens array plate 24, a second lens array plate 26 and a holder 30. The holder 30 includes: a first surface part 30a having a plurality of first through-holes 30e corresponding to a plurality of first outer lenses 24a; a second surface part 30b having a plurality of second through-holes 30f corresponding to a plurality of second outer lenses 26a; and a supporting part 30d for supporting the first surface part 30a and the second surface part 30b at positions separated for a predetermined distance. The first surface part 30a, the second surface part 30b and the supporting part 30d are integrally molded from light shielding material and the first lens array plate 24 and the second lens array plate 26 are inserted into a gap between the first surface part 30a and a third surface part 30c and a gap between the second surface part 30b and the third surface part 30c, respectively, to be held by the holder 30.
