An image lens array, from object side, comprises: a first positive meniscus plastic lens with a convex surface facing forward, a second negative meniscus plastic lens with a concave surface facing forward, a third positive meniscus plastic lens with a convex surface facing forward, and an infrared filter disposed in the lens barrel of the image lens array, the central thickness of the first and second lenses are: CT 1 <1.0 mm, CT 2 <0.6 mm. The radius of curvature of the front and back surfaces of the first lens are L 1 R 1 and L 1 R 2 that satisfy the condition as: |L 1 R 1 /L 1 R 2 |<0.5. The radius of curvature of the front and back surfaces of the third lens are L 3 R 1 and L 3 R 2 that satisfy the condition: |L 3 R 1 /L 3 R 2 |>0.3.
