Claim 6:
7. A method for manufacturing the resin laminated optical body according to claim 1, comprising:
a first step of preparing an optical base material having a curved surface;
a second step of forming an uncured resin layer on the curved surface of the optical base material;
a third step of preparing a flexible master having an inverted structure of a micro concave-convex structure formed on a surface and having flexibility;
a fourth step of bringing the flexible master into proximity to the uncured resin layer;
a fifth step of pressing the inverted structure of the flexible master against the uncured resin layer while applying a printing pressure to the flexible master to deform the flexible master; and
a sixth step of curing the uncured resin layer in a state where the inverted structure of the flexible master is pressed against the uncured resin layer to form a resin layer on the curved surface of the optical base material, wherein
in the fifth step, the printing pressure is adjusted to adjust a shape of the resin layer other than the micro concave-convex structure and a distance between the surface of the flexible master and the curved surface of the optical base material has a different value per region of the curved surface of the optical base material, and
an optical property provided for the resin laminated optical body depending on the shape of the resin layer other than the micro concave-convex structure is different from an optical property of the optical base material.
