Research Abstract	It was clarified that hydrogen-induced bending deformation was generated by means of the modification of surface layer of pure aluminum. To enhance the hydrogen absorption to aluminum, electro-less palladium coating was carried out prior to the hydrogen charging. It was also shown that the hydrogen-induced deformation was dependent on the thickness of palladium layer and the amount of hydrogen absorption. In addition to this, it was found that the specimen was recovered to the original flat shape when absorbed hydrogen was evolved from the bent specimen by heating.
