Pattern forming device using photo sintering and pattern forming method using same

Provided are a pattern forming device using photo sintering and a pattern forming method using the same, the device comprising a supply roll, an application device, a mask, a light generating device, and a collection roll. The supply roll supplies a flexible substrate. The application device applies conductive ink onto the substrate. The mask is positioned at an upper part of the substrate to which the conductive ink is applied such that a pattern is formed thereon. The light generating device emits light at the conductive ink applied to the substrate at an upper part of the mask so as to form a conductive pattern on the substrate. The collection roll collects the substrate having the conductive pattern formed thereon.
