Abstract

An imprint apparatus includes a deforming unit configured to deform the mold held by the mold holding unit into a convex shape toward the substrate; a driving unit configured to change an attitude of the mold or the substrate during a pressing in which the mold deformed is pressed against the uncured resin to thereby make a position of a contact region at which the mold is brought into contact with the uncured resin movable; a control unit configured to calculate a plane coordinates of a centroid of the contact region based on an image information of the contact region acquired by a measuring unit and to control an operation of the driving unit such that the plane coordinates position of the centroid is directed toward the plane coordinates position of the centroid of a pattern-forming region on the substrate, which has been calculated or has been acquired in advance.
