Therefore, by arranging the punched area 32 and the holeless area 34 adjacently along the axial direction of the rod of the filter segment 20, an area with relatively low airflow resistance and an area with relatively high airflow resistance are formed in the filter material 22 of one segment S of one sheet material 30. Therefore, it is possible to form a plurality of areas with different filtering performance, such as two, along the axial direction of the rod of the filter segment 20 using one filter material 22, while wrapping the outer periphery of the sheet material 30 with one wrapper 24 to maintain the rod shape of the filter segment 20.

For this reason, in this embodiment, the first additive L1 adheres to the holeless region 34 and does not adhere to the punched region 32 along the longitudinal direction of the sheet material 30.
