本发明提供一种成形物，其系具有发挥集光或光扩散效果之形状的成形物，其机械强度与耐热性优异，且具有高厚度偏差比。 本发明的成形物系含有环氧化合物(A)的硬化性组成物之硬化物，为由弯曲弹性系数[依据JIS K 7171(2008年)，惟，使用试验片(长度20mm×宽2.5mm×厚度0.5mm)，在支点间距离16mm测定]为2.5GPa以上的硬化物构成，且厚度偏差比(最厚部厚度/最薄部厚度)为5以上之具有集光或光扩散效果的成形物。本发明的成形物，较佳为最薄部厚度为0.2mm以下。作为前述硬化性组成物，较佳为光硬化性组成物。

Provided is a molded article having a shape that produces a light-focusing or light-scattering effect, the molded article having exceptional mechanical strength and heat resistance and a high thickness deviation ratio. This molded article is a cured product of a curable composition containing an epoxy compound (A), wherein the molded article comprises a cured article having a flexural modulus (measured in accordance with JIS K7171 (2008), using a test piece (20 mm long, 2.5 mm wide, and 0.5 mm thick) at a support point distance of 16 mm) of 2.5 GPa or greater, the molded article having a thickness deviation ratio (thickness at thickest portion/thickness at thinnest portion) of 5 or greater and exhibiting a light-focusing or light-scattering effect. This molded article preferably has thickness of 0.2 mm or less at the thinnest portion thereof. The curable composition is preferably a photocurable composition.
