RESIN SHEET, SUBSTRATE FOR ELECTRONIC COMPONENT, AND EVALUATION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin sheet having transparency, heat resistance and durability and having structural coloring property at a specified wavelength, and an evaluation method of the resin sheet.SOLUTION: The resin sheet comprises a resin (A) and particles (B), in which an average of an inter-particle distance of closest particles of the particles (B) calculated from a two-dimensional pattern by a grazing incidence small angle X-ray scattering (GISAXS) method is 100 nm or more and 300 nm or less.
