Abstract: Since structural portions of a device made of a plurality of materials are different from one another in mechanical hardness, it is very difficult to uniformly lap the structural portions.

Accordingly, in order to cope with the disadvantage, it is essential to surely grip abrasive grains of small size to a surface of a surface plate.
