Accordingly, the porous plate 110 may be easily manufactured in a form in which a plurality of holes 111a are formed through various embodiments such as the first embodiment or the second embodiment, and the air may be formed through the holes 111a. Can be passed smoothly.

In addition, the holes 111a provided in the porous plate 110 manufactured through the embodiments do not have edges on the inner circumferential surface because the cross-sectional shape is formed in a circular or elliptical shape as described above. That is, since the hole 111a forms an inner circumferential surface having no edges, the hole 111a may be applied to the inner circumferential surface thereof in a state where the adhesive 150 to be described later is evenly distributed.

In the present invention, the form of the second embodiment of the above-described embodiments can be described as a preferred embodiment, and with reference to this, other configurations of the present invention can be described as follows.

At this time, the fine irregularities 171 formed on the silicon member 170 may perform the same function as the above-described scratch (not shown).

Here, the silicon member 170 is provided through a primer, to protect the hole inner circumferential surface 111b from corrosion or physical impact, so that the subsequent coating (application of the adhesive 150) is smoothly made. It may be composed of a coating (塗料) to form a fine concave-convex 171 to. For example, the silicone member 170 may be composed of a thermosetting resin such as phenol resin, urea resin, melamine resin, polyester resin, epoxy resin, silicone resin, etc., but preferably, the silicone member 170 is composed of silicone resin.

Accordingly, since the silicon member 170 accommodates a part of the adhesive 150 applied to the inner surface through the fine irregularities 171, a large amount of the adhesive 150 applied to the inner surface may be applied.

Therefore, when the adhesive 150 is applied to the inner surface of the silicon member 170, the adhesive 150 may be applied to the inner surface of the silicon member 170 because the adhesive 150 is accommodated in the uneven portion 171. That is, the filter agent 130 is easily adhered to the inner surface of the silicon member 170 by a large amount of adhesive 150, and then can be firmly fixed.
