PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical article in which an optical adhesive agent is uniform in thickness.SOLUTION: A manufacturing method of an optical article provided with a bonding step in which an adhesive agent 18 having optical adhesive liquids 181 and 182 bonds a translucent member 14 and a crystalline substrate 17 to each other comprises: a blending step of dispersing spacer particles 131 and 132 to the optical adhesive liquids 181 and 182; a dropping step of dropping the optical adhesive liquids 181 and 182 dispersed with the spacer particles 131 and 132; and a holding step of pressing the crystalline substrate 17 against the translucent member 14, pressing and spreading the optical adhesive liquids 181 and 182 and holding the crystalline substrate 17 and the translucent member 14. In the blending step, a plurality of types of spacer particles 131 and 132 having compression displacement loads different from each other is used and each of the plurality of different types of spacer particles 131 and 132 is blended with the optical adhesive liquids 181 and 182. In the dropping step, the optical adhesive liquids 181 and 182 are dropped on a center portion A of the translucent member 14 and on a region other than the center portion A. |
