Summary: | A pattern transfer method for transferring an imprinting pattern formed on a mold provided with an alignment mark onto a substrate provided with an alignment mark or a resin material interposed between the substrate and the mold includes a first step for obtaining a first image by disposing the alignment mark provided to the mold and an alignment mark provided to a reference substrate at a first object position and observing the alignment marks through a first image pickup portion, a second step for obtaining a second image by disposing the alignment mark provided to the reference substrate at a second object position spaced apart from the first object position and observing the alignment mark through a second image pickup portion, and a third step for obtaining information about a difference in image position between the alignment marks by using the first and second images. |
