Abstract
A filter () has a cylindrical body (). The cylindrical body () is formed by laminating a plurality of pattern layers formed into a mesh form by a wire () in the radial direction. By repeating the traverse of the wire () and the reversal of the traverse direction in one winding end portion (L) and an other winding end portion (L), a plurality of turnaround points are set uniformly in the winding end portions (L, L). The shortest distance (X) in the circumferential direction between a first turnaround point (B) of the plurality of turnaround points in the other winding end portion (L) and a third turnaround point (B) at which the traverse direction is reversed immediately after being reversed at the first turnaround point (B) is longer than the shortest distance (Y) in the circumferential direction between the first turnaround point (B) and a fifth turnaround point (B) located nearest to the first turnaround point (B).
