しまうという不都合がある。First, as a melt blown nonwoven fabric filter medium,
As the material, a synthetic resin composed of a single substance or a mixture of polypropylene, polyester, Teflon, or the like can be used. The thickness is 0.18 to 0.30 mm, and the average fiber diameter is 2.
It is preferable to use one having a thickness of 10 to 10 μm and a basis weight of 10 to 60 g / m 2 . In the present invention, the reason why the above is preferable is that if the thickness is less than 0.18 mm, it is difficult to bond the filter medium and the filter medium is easily broken by itself. This increases the workability of the bending (packing) process, resulting in inconvenience. If the average fiber diameter is less than 2 μm, the pressure loss is too high, and the collection efficiency is too high. If the average fiber diameter is more than 10 μm, the collection efficiency is low. Further, if the basis weight is less than 10 g / m 2 , the trapping efficiency is low, and if the basis weight is more than 60 g / m 2 , there is a disadvantage that the pressure loss increases.

不都合がある。また、剛軟度（ＭＤ、ＣＤ方向とも）が
５００ｍｇ未満では、主濾材を補強するのに十分な強度
が得られなくなる不都合がある。Next, as the synthetic fiber nonwoven fabric filter material 2a, polyester, polypropylene, rayon, cotton, or the like can be used as a material, such as a thermal bond method, and the thickness is 0.29 to 0.48 mm. The average fiber diameter is 5 to 70 μm, and the basis weight is 40 to 150 g /
It is preferable to use those having m 2 and bristles (in both MD and CD directions) of 500 mg or more. The reason why the above is preferable is that if the thickness is less than 0.29 mm, it is not possible to obtain sufficient strength to reinforce the main filter medium, and if the thickness is more than 0.48 mm, the filter medium becomes too thick to be bent (packed). This is because there is a disadvantage that the workability of (working) is deteriorated. In addition, for those having an average fiber diameter of 5 to 70 μm, the pressure loss increases and the collection efficiency increases when the average fiber diameter is 5 μm, and the collection efficiency decreases when the average fiber diameter exceeds 70 μm. . Also, the basis weight is 40 g /
is less than m 2, the collection efficiency becomes low weight per unit area 1
If it exceeds 50 g / m 2 , there is a disadvantage that the pressure loss increases. On the other hand, if the stiffness (in both the MD and CD directions) is less than 500 mg, there is a disadvantage that sufficient strength for reinforcing the main filter medium cannot be obtained.

8 mmAq or less can be secured. If the area of the filter medium is less than 14 m 2 / unit, there is a disadvantage that the amount of retained dust is reduced,
On the other hand, when the filter medium area is 16 m 2 / unit, the pressure loss increases,
There is a disadvantage that the amount of dust retained until the final pressure loss is reduced.
