An image pickup apparatus includes an image forming optical system which includes an aperture stop and a plurality of lens components, and an image pickup section which is disposed on an image side of the image forming optical system, and has a light-receiving surface which is not flat and is curved to be concave toward the image forming optical system. The image forming optical system includes a first lens component having a negative refractive power, a second lens component having a positive refractive power, and a third lens component having a positive refractive power. A shape of the first lens component is a meniscus shape, and a shape of the third lens component is a biconvex shape, and the following conditional expressions (1) and (2) are satisfied: 0.7<|PS×Rimg|<1.5  (1), and0.7<|θout 90/θimg 90|<1.5  (2).
