Problem to be solved. To provide a gripper in which an opening between front edges of a gripping part can be suppressed when a workpiece is gripped by the gripping part and thereby the workpiece gripped by the gripping part is never cut. Solution. In a gripper 10, a gripping part 22 of an arm 14 that is one of a pair of arms 12,14 is composed of an elastic piece 24 with a rear end extended toward the rear end side of the arm 14. The elastic piece 24, in state where a gripping surface 22a is in surface contact therewith, is deformed against the elasticity so that the surface contact with the gripping part 20 can be held when both the arms 12,14 are operated in a closing direction.
