Abstract
In an image sensor in which each microlens of a microlens array is disposed at a position corresponding to each pixel on a side to which light flux is incident, a layer formed of a member different from a member constituting the microlens array is disposed on the side of the microlens array to which light flux is incident, and a surface of the layer formed of the different member has a phase structure optically-opposite to that of the microlens array.
