Abstract: A light absorption anisotropic layer which has a high S/N ratio for generating polarized light with respect to rays in an infrared wavelength region, is lightweight, and has excellent handleability, a laminate, and a sensor system including the light absorption anisotropic layer or the laminate. The light absorption anisotropic layer contains a dichroic coloring agent having a maximal absorption at a wavelength of 700 to 1500 nm, in which an average absorbance at a wavelength of 850 nm is 0.24 to 0.50 and a thickness is 5 ?m or less.

Abstract: A conical-projections-sheet packaging body includes a conical-projections sheet, a conical-projections forming sheet, and a sealing sheet. The conical-projections sheet includes a substrate and a plurality of conical projections formed on a surface of the substrate. The conical-projections forming sheet has a plurality of conical-recess parts, which is used to form the plurality of conical projections and wherein the plurality of conical projections is disposed. The conical-projections forming sheet protects the conical projections in a state wherein the plurality of conical projections is tightly adhered to the surface of the substrate. The sealing sheet, by being fixed to the conical-projections forming sheet, seals the conical-projections sheet between the conical-projections forming sheet and the sealing sheet.
