An optical lens and an electronic device comprising same. The optical lens sequentially comprises, from an object side to an image side along an optical axis: a first lens (L1) having a negative focal power, an object side surface (S1) of the first lens being concave; a second lens (L2) having a positive focal power; a third lens (L3) having a positive focal power, an object side surface (S6) of the third lens being convex, and an image side surface (S7) of the third lens being convex; a fourth lens (L4) having a positive focal power; a fifth lens (L5) having a negative focal power; a sixth lens (L6) having a focal power; and a seventh lens (L7) having a negative focal power; the number of lenses having refractive powers in the optical lens assembly is seven.
