Photographing optical lens assembly and electronic device

A photographing optical lens assembly comprising five lens elements, the five lens elements being, in order from an object side to an image side:

• a first lens element having an object-side surface being convex in a paraxial region thereof;
• a second lens element;
• a third lens element having an object-side surface being convex in a paraxial region thereof;
• a fourth lens element having an image-side surface being convex in a paraxial region thereof;
• and
• a fifth lens element having an image-side surface being concave in a paraxial region thereof, and the image-side surface of the fifth lens element having at least one convex shape in an off-axis region thereof;
• wherein an Abbe number of the third lens element at a wavelength of helium d-line is Vd3, an Abbe number of the fourth lens element at the wavelength of helium d-line is Vd4, an Abbe number of the fifth lens element at the wavelength of helium d-line is Vd5, an axial distance between the object-side surface of the first lens element and the image-side surface of the fifth lens element is TD, an axial distance between the image-side surface of the fifth lens element and an image surface is BL, and the following conditions are satisfied:
• 15<Vd3+Vd4+Vd5<75;
• and
• 3.50<TD/BL<20.
