Abstract
A suction method is provided as a method of performing, by using a suction collet, suction of a Fabry-Perot interference filter including: a substrate; a laminated structure that is provided on the substrate and that includes a main surface facing a side opposite to the substrate; and a thinned portion that is located outside the laminated structure when viewed in a direction intersecting the main surface and that is recessed to a side of the substrate with respect to the main surface, the method including: a first step of arranging the suction collet so as to face the main surface; a second step of bringing the suction collet into contact with the Fabry-Perot interference filter after the first step; and a third step of suctioning the Fabry-Perot interference filter by using the suction collet after the second step.
