Abstract
In a main body of a filter apparatus, an internal space A corresponding to a flow path of gas is formed in an annular shape, and a filter material filled in the internal space A is disposed in an annular shape. For this reason, it is possible to keep a cross-sectional area of the filter material large when compared to a case in which the filter material is disposed in an elongated shape, reduce flow path resistance, and keep a speed (linear velocity) of gas passing through the inside of the filter material low. Further, it is possible to improve capturing efficiency of the filter material. In addition, one end edge of a flow path, and flow paths and are formed at one end of the main body.
