Abstract
An elastic resin sheet that is a resin sheet formed using a resin composition containing a thermosetting resin and a curing agent, in which when a maximum height of a surface roughness on a first surface of the resin sheet is Rz1 (μm), a maximum height of a surface roughness on a second surface facing the first surface is Rz2 (μm), and a thickness is t (μm), the Rz1, the Rz2, and the thickness t (μm) satisfy relation of the following Formula (1): (Rz1+Rz2)/t≤0.5 (1), the elastic resin sheet includes a light-diffusing portion having irregularities with an arithmetic mean roughness Ra of 0.3 μm or more and 5.0 μm or less on at least one of the first surface and the second surface, and the elastic resin sheet has an initial tensile modulus of 0.5 MPa or more and 500 MPa or less.
