The purpose of the present invention is to provide a covering material, which can exhibit an appropriate gripping property for grasping various objects to be grasped according to the object, and a covering structure for a robot grasping unit. The problem is solved with a covering material characterized: in the covering material being provided with an inner layer (121), which is provided on the surface of a substrate (11) with an object-grasping function and which is obtained from an elastic substance, and an outer layer (122), which is on the surface of the inner layer (121) and is obtained from an elastic substance that contacts the object when the object is grasped; in the inner layer (121) being adhesive and configured from an elastic substance with a lower hardness than the outer layer (122); in the outer layer (122) having at least one penetration (13), which penetrates so as to reach the inner layer (121); and when acted upon by the stress of grasping an object, in the covering material being configured so that a portion of the inner layer (121) enters the penetration(s) (13) or protrudes from said penetration(s) (13) according to the magnitude of said stress. |
