Abstract
A novel mold is provided. The mold is prepared through steps of forming a concavo-convex pattern on a substrate, forming a film by embedding a material of a composition having shape-memory in the concavo-convex pattern, and forming a mold having the concavo-convex pattern by separating the film from the concavo-convex pattern after the film formation in the film formation step.
