Abstract
An imprint mold including a substrate of transparent material having a first principal surface having a pattern region and a second principal surface; a first light shielding film provided on the first principal surface, along a periphery of the pattern region; and a second light shielding film provided on the second principal surface, having an opening including an opposite region to the pattern region, a part of the second light shielding film opposite to the first light shielding film. In a cross section perpendicular to the substrate, the maximum incident angle of the light for curing a transfer layer to the second principal surface is less than an angle between a perpendicular line of the second principal surface and a line connecting an end of the second light shielding film on a side of the opening and a farthest end of the first light shielding film from the pattern region.
