An optical image lens system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element has positive refractive power. The second lens element has positive refractive power. The third lens element has positive refractive power. The fourth lens element has refractive power. The fifth lens element with refractive power has an image-side surface being convex in a paraxial region thereof, wherein at least one surface of the fifth lens element is aspheric. The sixth lens element with refractive power has an image-side surface being concave in a paraxial region thereof, wherein at least one surface of the sixth lens element is aspheric, and the image-side surface of the sixth lens element has at least one inflection point thereon.
