Abstract

The present invention relates to a roll stamp and a method of manufacturing the same, the roll stamp including a cylindrical metal mold including a debossed pattern formed on an outer side and a hollow portion formed on an inner side, and a dummy roller inserted into the hollow portion. Because a joining portion is not formed on the entire area of the cylindrical metal mold, a problem in which edge regions are separated does not occur. Also, due to the absence of the joining portion, it is possible to perform a patterning process continuously.
