PROBLEM TO BE SOLVED: To improve transparency and realize suitable application to an electromagnetic wave shield filter or the like of an image display, by defining the width of lines and the pitch of a pattern of a conducting part constituted of the lines drawing a pattern composed of many angular pieces having identical shapes. SOLUTION: Special ink containing conductive powder using metal single element such as gold, silver, platinum, palladium, nickel, copper and aluminum is screen-printed on the surface of a polyethylene terephthalate resin film, by using a PDP screen printer and a metal mesh screen formed of stainless of 500 mesh. A conducting part wherein square patterns are drawn in a lattice with 5-25μm line width and 50-2000μm pitch of the patterns is formed, and an electromagnetic wave shield member is manufactured. Thereby transparency can be improved, and effective application to an electromagnetic wave shield filter or the like of an image display is enabled.
