摘要： Provided is a substrate for mounting an LED that can be applied to a thin base material and can result in a sufficient reflectance, particularly a substrate for mounting an LED, adaptable to a mini-LED and a μ-LED. In the substrate for mounting an LED, including a base material and a reflective layer that is layered on an upper region thereof, plural openings are disposed at generally equal spacings in longitudinal and lateral directions in the reflective layer, respectively, the reflective layer is the cured product of a curable resin composition including a curable resin and titanium oxide, the cured product has a storage elastic modulus of 4.0 GPa or less at 25° C., the spacings between the opening and the opening adjacent thereto in the longitudinal direction and the lateral direction are not less than twice the lengths of the opening in the longitudinal direction and the lateral direction, respectively, and the total area rate of the openings with respect to the area of the reflective layer is 0.1% or more and 9.0% or less.
