ら、吸着保持出来なかった。2. Description of the Related Art Generally, as a transfer device for articles having a smooth surface such as glass or cardboard box and having no air permeability,
Various types having a suction pad have been proposed and put into practical use. In this type of transfer device, since the article to be transferred is held on the suction pad by depressurizing the closed space formed by the suction pad and the article to be transferred, the article to be transferred is, for example, a filter having air permeability. A porous body such as a printed circuit board having a plurality of through holes for mounting elements and electronic components cannot be adsorbed and held because the closed space cannot be sufficiently depressurized.

されている。Therefore, when transferring these porous bodies, a method of holding them with a hand and carrying them or carrying them with a conveyor or the like is adopted. However, in a flat plate-shaped porous body such as a printed circuit board, it is difficult to hold it with a hand because of its shape, and when it is conveyed by a conveyor or the like, positioning work becomes complicated, so that it is part of it. By forming an adsorbed part that does not have air permeability,
A transfer device for adsorbing and holding this adsorbed portion and transferring it has been put into practical use.

る。However, when the adsorbed portion having no air permeability to the porous body is formed, for example,
In the printed circuit board, there is a problem that a circuit cannot be built in that portion and the entire porous body cannot be effectively used. Although it is possible to remove the adsorbed portion in the final step of processing the porous body, there is a problem in that the transfer of the final product becomes complicated. In addition, if the suction pad is not sucked onto the suction target portion accurately, the porous body may drop out or be displaced during the transfer, and the transfer device is complicated because the suction pad is positioned with respect to the porous body. However, there is a problem in that the transfer becomes longer and the transfer time becomes longer.

An expensive one having a control means or the like is required as the transfer means. An object of the present invention is to provide an adsorption holding device capable of directly adsorbing and holding a porous body and an adsorption holding method using the same.
