PROBLEM TO BE SOLVED: To regulate protrusion of an adhesive agent from an outer periphery part of a substrate within predetermined width.SOLUTION: In a substrate sticking method for sticking a plurality of substrates, a photo-curing type adhesive agent 3, disposed between a plurality of substrates 1 and 2 by an overlapping process, is spread toward an outer periphery from a center of one joint surface 1a of the plurality of substrates 1 and 2, and an amount of protrusion is reduced as much as possible by irradiating light toward a side face of the outer periphery of the adhesive agent 3 by a light irradiating process, even if the adhesive agent 3 protrudes from an outer periphery part of the plurality of substrates 1 and 2. |
