Abstract

The method for fabricating pattern of a cured product includes a first step (arranging step) of arranging a layer formed of a liquid film of a curable composition (α1) containing at least a component (A1) serving as a polymerizable compound on a substrate and a second step (dispensing step) of dispensing liquid droplets of a curable composition (a2) containing at least a component (A2) serving as a polymerizable compound discretely onto a layer formed of a composition (α1') of components of the curable composition (α1) except a component (D1) serving as a solvent, in which: the mixing of the composition (α1′) and the curable composition (α2) is exothermic.
