Abstract: A laminate includes: a void-containing layer and a pressure-sensitive adhesive/adhesive layer. The pressure-sensitive adhesive/adhesive layer is directly laminated on one surface or both surfaces of the void-containing layer. The pressure-sensitive adhesive/adhesive layer contains a (meth)acrylic polymer, and nanoindentation hardness of the pressure-sensitive adhesive/adhesive layer is 0.1 MPa or more and 1.0 MPa or less.

Abstract: Provided is a light extraction member which can be obtained at an adequate cost, while achieving desired light output characteristics without requiring complicated design and structure, and which is easily combined with another member, while exhibiting excellent productivity and excellent handling properties. A light extraction member according to the present embodiment includes: a light guide part which has a first main surface being on the light output side and a second main surface being on the reverse side of the first main surface; and a light output control layer which is a predetermined pattern formed on the first main surface. With respect to this light extraction member, the refractive index n1 of the light guide part and the refractive index n2 of the light output control layer satisfy relational expression n1>n2; and the refractive index n2 of the light output control layer is from 1.01 to 1.30.
