| description | An aspect of the invention relates to an optical body (1) comprising: a base material (10) configured to propagate light incident inside the base material (10) from a side face of the base material (10); a second optical layer (12), formed on at least one surface of the base material (10), configured to reduce a reflection of extraneous light at the surface of the base material (10), wherein the second optical layer (12) includes a second concave-convex (12c) in which an average cycle of concavities and convexities is lower than a visible light wavelength band; and a first optical layer (11), laminated on top of a part of the second optical layer (12), configured to extract internally propagating light incident inside the base material (10) to an outside of the base material (10), wherein on a surface of the first optical layer (11), a first concave-convex structure (11c) configured to reflect the internally propagating light is formed, wherein the first concave-convex structure (11c) includes a number of first convexities (11a) and first concavities (11b), wherein the first convexities (11a) have a shape protruding outward in a thickness direction of the optical body (1), while the first concavities (11b) have a shape depressed inward in the thickness direction of the optical body (1). Further aspects relate to a method for manufacturing an optical body and a light-emitting apparatus. |
