An optical lens assembly and an imaging device. The optical lens assembly includes, 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.
