The invention discloses an imaging lens. The imaging lens sequentially comprises a first lens body, a second lens body, a third lens body, a fourth lens body and a fifth lens body along an optical axis from the object side to the image side. The first lens body has positive focal power, the object side face of the first lens body is a convex face, and the image side face of the first lens body is a convex face. The second lens body has negative focal power; the third lens body has positive focal power, the object side face of the third lens body is a convex face, and the image side face of the third lens body is a convex face. The fourth lens body has positive focal power, the fifth lens body has negative focal power, and the face inclination angle beta 5 of the maximum effective radius position of the object side face of the fifth lens body is larger than -20 degrees and smaller than 5 degrees.
