摘要： A wide-angle lens (100) includes a front group (110), an aperture (80), and a rear group (120). The front group (110) includes a first lens (10) and a second lens (20) arranged from a side (La) closest to an object to an image side (Lb). In such a wide-angle lens, to suppress an occurrence of a ghost caused by multiple reflection between a lens surface (102) of the first lens (10) on the image side (Lb) and a lens surface (21) of the second lens (20) on the object side (La), the sag amount Sag21 (mm) and the diameter D21 (mm) of the lens surface (21) satisfy the following conditional expression: 0
