This suction device 10 is composed of the suction cup 12, a center shaft 14, a case 16, a displacement mechanism 18, and so on. The suction cup 12 is formed into a disk-like shape, and has one surface in a thickness direction as the recessed adsorption surface 20 and the other surface as a projecting back surface 22. The suction cup 12 has a disk-like suction cup body 24 and a gel layer 26. A projecting piece 32 projecting outward in a radial direction is provided integrally with the suction cup body 24 on the periphery of the suction cup body 24. The suction cup body 24 is attached with a gripping member 30 for detaching the suction cup, and the gripping member 30 is attached to the projecting piece 32. The gripping member 30 is grippably formed from material having an elastic modulus lower than that of elastic material forming the suction cup body 24 (including material having no elastic modulus).
