An optical imaging lens includes a first lens element to a sixth lens element. The first lens element has positive refracting power, an optical axis region of the object-side surface of the second lens element is convex, the third lens element has positive refracting power and an optical axis region of the image-side surface of the third lens element is convex, and an optical axis region of the image-side surface of the fifth lens element is convex. ImgH is an image height of the optical imaging lens, Fno is the f-number of the optical imaging lens, υ2, υ3, υ4 and υ6 are respectively an Abbe number of the second, the third, the fourth and the sixth lens element to satisfy ImgH/Fno≥2.000 mm and υ2+υ3+υ4+υ6≤135.000.
