Abstract:
To provide an image sensing lens and an image sensing module each of which includes four lenses and each of which corrects aberrations well and has a great resolving power and a reduced height, an image sensing lens includes (i) a third lens which has a surface facing an image surface, the surface being an aspheric surface and (ii) a fourth lens which has a surface facing an object and a surface facing the image surface, the surfaces being each an aspheric surface. The image sensing lens satisfies the following Formulae (1) through (3): 0.51 20 (3).
