PROBLEM TO BE SOLVED: To provide a suction cup having excellent sucking force even if the same is applied to a rough surface or a curved surface. SOLUTION: The sucking cup applicable to the rough surface and/or the curved surface consists of a suction cup main body including a round dome shape suction cup main body made of elastic body, and an incidental sheet part joined to a bottom surface part of the suction cup main body having the round dome shape. The incidental sheet part is a sheet material of predetermined hardness and strength having elasticity provided with a adhesion agent layer on a lower surface. A flat surface shape of the incidental sheet part includes an opening part opening at a recess part of the suction cup main body on a part inside more than a joining part with the suction cup main body. A wide area part largely extending to an opposite side of a loading direction of the suction cup main body in relation to a joined suction cup main body position at least at a time of use is included. A detachment grip part positioned at least on the opposite side in relation to the wide area part in the loading direction is provided. COPYRIGHT: (C)2006,JPO&NCIPI
