PROBLEM TO BE SOLVED: To provide a gripping device of an industrial robot capable of easily gripping plural plate bodies in a stacked state through their stacked side surfaces. SOLUTION: Gripping fingers 4 to take gripping motion are provided on a base plate 3 facing against each other and a gripping member 7 forming a bag shape by sealing a fluid material 8 in it is provided on gripping surfaces of the gripping fingers 4. Thereafter, respective stacked side surfaces of a plural number of plate bodies in an stacked state are pressurized and gripped through the gripping member 7. Consequently, the gripping member 7 is deformed by flowing work of the fluid material 8 regardless of deformation of the gripping fingers 4 in the gripping motion and an error of dimensions of respective gripping parts of plate bodies in the stacked state and pressurizes the side surfaces of the plate bodies. Accordingly, no clearance is produced between the gripping fingers 4 and the side surfaces of the plate bodies, and occurrence of insufficient gripping is prevented and nonconformity due to the insufficient gripping is eliminated.
