PURPOSE: To realize the sure suction an fixation of a work on a surface layer without conducting masking around the work on the upper surface of the surface layer to fix the work and reduce drastically the cost of manufacture with simple structure.

CONSTITUTION: This is made up by having a base stand 51 having an air intake passage to penetrate upward and downward; and a multilayer body consisting of layered slablike bodies of plural kinds mounted on the base stand 51. The slablike bodies of plural kinds constituting the multilayer body are made up at least of the surface layer member 54 of a sheet that is arranged on the uppermost layer of the multilayer body and is equipped with a number of micro penetration holes which are distributed in approximate uniformity, and has the quality of ventilation; and a second layer member 53 of a porous body that is arranged on the lower surface of the surface layer member 54 and possesses three-dimensional mesh structure, and depressurize the inside of the multilayer body through the air intake passage of the base stand 51 by means of a sucking means.
