The present invention relates to an optical lens assembly and an imaging device. The optical lens assembly comprises, in order from an object side to an image side: a first lens (L1) being a meniscus lens having a negative focal power, the first lens having an object side surface (S1) being a convex surface, and an image side surface (S2) being a concave surface; a second lens (L2) having a negative focal power, an image side surface (S4) of the second lens being a concave surface; a third lens (L3) being a meniscus lens having a positive focal power, the third lens having an object side surface (S5) being a concave surface, and an image side surface (S6) being a convex surface; a fourth lens (L4); a fifth lens (L5) cemented to the fourth lens; and a sixth lens (L6) having a positive focal power. With the optical lens assembly and the imaging device according to the present invention, high resolution can be obtained while maintaining the miniaturization of the optical lens assembly.
