リング状形状を長期に渡って維持できる。As described above, in the present invention, a ring-shaped body having an abutting portion in the radial direction and having a large number of planar ring-shaped cross-sectional corrugated portions extending outward is a weekly holiday, and the abutting portion of the filter body is and a striped connecting element that is connected to a base member and maintains a ring-like shape, the connecting element is provided on both sides of the base member and the cross-sectional corrugated portion at the abutting portion. and a concave-shaped connecting portion that receives the cross-sectional corrugated portion and is connected to the cross-sectional corrugated portion, so that the cross-sectional corrugated portions at the abutting portion are reliably and firmly connected to the connecting element, and the cross-sectional corrugated portions at the abutting portion are not connected to each other as in the conventional case. The strength of the bonded portion is higher than that of a structure in which the filter elements are directly bonded and bonded, and therefore, separation of the abutting portion at the bonded portion can be suppressed, and the ring-shaped shape of the filter element can be maintained for a long period of time.
また、結合要素は筋状であるため、上記効果を発揮しな
がらも断面波形部に対する該結合要素の占める割合が少
