An optical imaging lens includes a first lens element to a sixth lens element. The third lens element has negative refracting power and a periphery region of the image-side surface of the third lens element is convex. An optical axis region of the image-side surface of the fourth lens element is convex, an optical axis region of the image-side surface of the fifth lens element is convex, and an optical axis region of the object-side surface of the sixth lens element is concave to satisfy ν2+ν3+ν4+ν6≤130.000 and (T1+T4+G45)/(G12+T2+G34)≥2.500.
