  • the core 11a and the sheath 11b are configured to have different total finenesses and additive rates of the plasticizer from each other such that the core 11a becomes harder, and the sheath 11b becomes softer; therefore, even if the sheath 11b is squeezed when passing through the above narrower section 48, the sheath 11b absorbs an external pressure in a manner as to reduce the pressure to be applied onto the core 11a. Accordingly, it is possible to reduce deformation in shape of the through hole 10.
  • at least the core 11a has a smaller diameter than the width of the narrower section 48, which prevents the through hole 10 from being directly squeezed. For example, as shown in FIG.

In the hollow filter 11 including the hole 35, it is also possible to prevent crush, deformation or the like of the hole 35.
  • the hole 35 may be formed by introducing the core forming fibers 4 into the hole forming tube through insertion and pull-out of the mandrel 19 in the hole forming device 9.
  • each filter for measurement M was placed on a stage 56 as shown in FIG. 13 , and a pressing member 53 having a diameter of 15 mm was brought into contact with the filter for measurement M from above the filter for measurement M so as to pressurize the filter for measurement M at a weight of 300 g for 10 seconds (in a direction indicated by an arrow L in FIG. 13 ).
  • Hardness (mm/10) is defined by the following formula, where h1(mm) denotes a distance between an upper surface of the stage 56 and a pressing surface of the pressing member 53 when the pressing member 53 was brought into contact with the filter for measurement without applying the weight of 300 g; and h2 (mm) denotes a distance between the upper surface of the stage 56 and the pressing surface of the pressing member 53 when the filter for measurement was pressurized for 10 seconds.
  • Hardness mm / 10 h 1 ⁇ h 2 ⁇ 10
  • each hollow filter including a sheath and a core In measurement of the hardness of each hollow filter including a sheath and a core , the hardness of each sheath was measured by using filters each having the core , the sheath, and wrapping paper as the filters for measurement M (the wrapping paper, and the boundary line between the core and the sheath are not shown); the hardness of each core was measured by using filters each including only a core as the filters for measurement M.
  • each hollow filter 11 (the wrapping paper 30 is omitted in the drawing) of Sample 1 to Sample 3, which had a diameter of approximately 7.6 mm, a core diameter of approximately 5.0 mm, and a length of approximately 84 mm, was held between two metal plates 52, and the hollow filter 11 was pressurized until a distance between the two metal plates 52 became 6.0 mm.
  • respective shapes of a through hole of each filter before the pressurizing, during the pressurizing, and after the pressurizing (immediately after the pressurizing) were photographed for the purpose of measuring a distortion rate of a hole diameter in each filter.
  • a longer diameter having a longer length was defined as A
  • a shorter diameter having a shorter length was defined as B
  • the distortion rate (A/B) was calculated.
  • An average value of this rate was also calculated for each sample. A smaller distortion rate indicates that the shape of the through hole is better retained against an external pressure.
  • the same pressurizing test was conducted in the same manner on Sample 4 to Sample 6 that are the filters of the comparative.
  • the results were such that the average value of the distortion rate before the pressurizing was 1.02 in each Sample of the example and the comparative.
  • the average value of the distortion rate during the pressurizing was 1.22 in the example, and 2.07 in the comparative, which indicates that the shape of the through hole was better retained in the example than that in the comparative.
  • the average value of the distortion rate after the pressurizing was 1.03 in the example, and 1.29 in the comparative , which also indicates that the shape of the through hole was better retained in the example.
