多孔質固定基板８の面上を移動可能に構成されている。EXAMPLE Hereinafter, an apparatus for forming a conductive layer pattern on a green sheet according to an example of the present invention will be described with reference to the drawings. In FIG. 1, 8 is a fixed substrate made of a rigid porous material such as sintered metal, and 9 is a fixed substrate made of a flexible porous material such as toilet vapor. This is a formed sheet-like body. Both ends of this sheet-like body 9 are fixed to the supply Lee/L/10 and the winding-/I/11, respectively, and the winding! It is configured to be movable on the surface of the porous fixed substrate 8 as J-/L'll rotates.

状体９が供給されるように動作する。With the sheet-like body 9 stopped, a green sheet 1 with a via hole lv6 is placed on the sheet-like body 9, and while suction is applied from below the porous fixed substrate 8, a screen is drawn as in the conventional method. A conductive layer pattern 5 is formed by a printing method. At this time, the porous fixed substrate 8 and the sheet-like body 91 are placed in the beer hole /l/6 of the green sheet 1.
An attractive force acts through the pier hole 6, and a conductive layer is formed within the pier hole 6 as well. After the green sheet on which the conductive layer is formed is removed and before the next green sheet is placed, winding-A/1 is performed in conjunction with the green sheet removal operation, for example.
ff is rotated by a predetermined angle, the sheet-like body 9 contaminated with the conductive paste 5 is wound up for a predetermined length, and a new sheet-like body 9 is supplied.
