摘要： An image pickup lens 10 includes a first lens L1, a second lens L2, and a third lens L3. An image pickup surface I of a solid-state image sensor 51 is curved into the shape of a shallow concave spherical surface. By forming an image side surface 3b of the third lens L3, which is the lens nearest to the image side, into an aspherical shape, it is possible to make a curvature of field suitable to the curved image pickup surface I while securing excellent telecentric characteristics. The above image pickup lens 10 satisfies conditional expression (1) where THID is a thickness of an outermost periphery PA of the lens L3 nearest to the image side along an optical axis direction AX and THIC is a thickness of the lens L3 nearest to the image side on the optical axis AX.
