Abstract
To provide a curable composition for nanoimprinting that can form a cured product that has a sufficiently cured surface and is less prone to a pattern collapse defect even when the curable composition is cured by a photo-nanoimprint method at a low exposure dose. To provide a nanoimprint method for forming such a cured product. To provide a cured product that is less prone to a pattern collapse defect even when cured at a low exposure dose, a method for producing such a cured product, a method for manufacturing an optical component, a method for manufacturing a circuit board, and a method for manufacturing an electronic component.A curable composition that satisfies the formula (1) in a cured state: Er1/Er2≥1.10 (1)
