METAL MESH

PROBLEM TO BE SOLVED: To provide a manufacturing method of a metal mesh by which wettability and pass through property can be obtained and the metal mesh. SOLUTION: The molecular bond of the surface of a wire material constituting the metal mesh 1 are surface reformed by a plasma P irradiated from a plasma irradiating device 4 to sufficiently uniformly form a plasma coating Pa with high wattability (affinity) on the whole surface of the wire material 2. Foreign materials E sticking to the surface of the wire material 2 is separated and removed from the surface of the wire material 2 by bonding the same to the molecules of the plasma P or making the plasma colliding against the same. The pass through property suitable fine screen printing or a filter for separating fine foreign objects can be obtained because the wettability is improved and the surface tension and contact resistance provided to objects to be contacted are reduced by forming a large number of fine unevenness on the whole surface of the wire material 2 and the plasma coating Pa.
