A suction method of performing suction of a Fabry-Perot interference filter including a substrate and a laminated structure that is provided on the substrate and that includes a main surface facing a side opposite to the substrate, by using a suction collet, the method comprising: 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, wherein the suction collet includes: a main body having a surface; and a contact portion that is provided on the surface so as to protrude from the surface and that includes a pair of first contact surfaces each provided with an opening for air intake, the laminated structure includes: a membrane structure including a first mirror portion and a second mirror portion facing each other via a gap and in which a distance from each other is variable, and including a portion of the main surface; and a pair of first electrode terminals disposed so as to face each other via the membrane structure when viewed in a direction intersecting the main surface, in the first step, the suction collet is disposed such that the surface faces the main surface and each of the first contact surfaces faces a corresponding first electrode terminal of the pair of first electrode terminals, in the second step, each of the first contact surfaces is brought into contact with the corresponding first electrode terminal of the pair of first electrode terminals, and in the third step, each of the first electrode terminals is suctioned to a corresponding first contact surface of the pair of first contact surfaces by air intake through the opening provided on the corresponding first contact surface. 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, wherein the suction collet includes: a main body having a surface; and a contact portion that is provided on the surface so as to protrude from the surface and that includes a pair of first contact surfaces each provided with an opening for air intake, the laminated structure includes: a membrane structure including a first mirror portion and a second mirror portion facing each other via a gap and in which a distance from each other is variable, and including a portion of the main surface; and a pair of first electrode terminals disposed so as to face each other via the membrane structure when viewed in a direction intersecting the main surface, in the first step, the suction collet is disposed such that the surface faces the main surface and each of the first contact surfaces faces a corresponding first electrode terminal of the pair of first electrode terminals, in the second step, each of the first contact surfaces is brought into contact with the corresponding first electrode terminal of the pair of first electrode terminals, and in the third step, each of the first electrode terminals is suctioned to a corresponding first contact surface of the pair of first contact surfaces by air intake through the opening provided on the corresponding first contact surface.
