Patent ID: 7449042

Claim:
A filtering member comprising a cylindrical body formed by winding a wire there for filtering and cooling a gas by allowing the gas to pass through from an inside to an outside in a radial direction, wherein the cylindrical body is formed by laminating a plurality of pattern layers in the radial direction, the pattern layers being formed into a mesh form by traversing the wire between one winding end portion and an otherwinding end portion in an axial direction of the cylindrical body while a traverse direction of the wire is reversed in one winding end portion and the other winding end portion, in the other winding end portion, a plurality of reversal positions are set to reverse the traverse direction of the wire, and a shortest distance in a circumferential direction between a first reversal position of the plurality of reversal positions and a second reversal position at which the traverse direction is reversed immediately after being reversed at the first reversal position is longer than a shortest distance in the circumferential direction between the first reversal position and a third reversal position located nearest to the first reversal position.
