In a system for transferring a plate-shaped member with interleaving paper thereon, a suction adhesion device included in a suction adhesion unit includes suction pads that adhere to a surface of a glass plate by suction with interleaving paper in between the surface and the suction pads; an air blowing device blows air between the adhered glass plate and a glass plate positioned below the adhered glass plate; a robot moves the suction adhesion unit; a clamping device includes a pair of pushing members that are arranged at both sides, respectively, of the glass plates and move toward the glass plates to come close to each other; and at least before the suction adhesion unit lifts the adhered glass plate, a controller causes the pair of pushing members to move to push protruding portions of pieces of interleaving paper, the protruding portions protruding from the sides of the glass plates.
