Abstract
An optical low-pass filter is arranged on an object side than an image sensor in an image pickup apparatus and has an unevenness shape. The conditions of 5.0 μm≤Δz≤80.0 μm and 1.0≤Ps/<Pf>≤20.0 are satisfied where Δz represents a distance between the optical low-pass filter and the image sensor, Ps represents a pixel pitch of the image sensor, and <Pf> represents an average pitch of the unevenness shape.
