Abstract: A photographing optical lens assembly includes, in order from object side to 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 with negative refractive power has an object-side surface being convex in a paraxial region and an image-side surface being concave in a paraxial region. The third and fourth lens elements have refractive power. The fifth lens element with refractive power has an object-side surface being convex in a paraxial region. The sixth lens element with negative refractive power has an image-side surface being concave in a paraxial region, and an object-side surface and the image-side surface of the sixth lens element are aspheric. The image-side surface of the sixth lens element has at least one inflection point.
