A gripping device is equipped with an abutment member that is annexed on a region of a gripping portion that abuts on a work. The abutment member is equipped with an inner bag that is made of a material having elasticity, a particulate matter with which the inner bag is filled, and an outer bag that covers the inner bag. The particulate matter is hardened while being deformed into a shape matching a contour of the work by increasing a ratio of a volume of the particulate matter to an inner volume of the inner bag with the work gripped by the gripping portion. A reverse face of the outer bag and a surface of the inner bag have a light-emitting portion therebetween. Thus, a rupture created in the outer bag can be detected, and the breakage of the inner bag can be obviated.
