ABSTRACT:
One object of the present invention is to provide a chucking apparatus and its production method that is capable of carrying out holding, alignment, transport and so forth without causing problems such as the generation of particles. In order to achieve this object, the present invention provides a chucking apparatus provided with a base in which protrusions or grooves are formed on one of its faces to form an irregular surface, and the apical surfaces of protrusions of the irregular surface serve as a chucking surface for chucking and holding a plate-shaped sample, wherein the apical and lateral surfaces of the above protrusions, and the bottom surfaces of the above indentations, are all polished.
