PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding member which is manufactured through a flexographic printing method capable of coping with productivity, quality, quantity, and cost; and comprises a film base material and a mesh that is made of ink having an electromagnetic wave shielding effect and formed on one surface of the film base material. SOLUTION: A pattern of electromagnetic wave shielding ink comprising two or more ink lines each of which has a width of L and crosses with each other to form a mesh is provided on one surface of the film base material to form the electromagnetic wave shielding member, and the intersections of the ink lines are each 1.2 to 3 times as thick as the ink line. Or, the electromagnetic wave shielding member is composed of a pattern of the electromagnetic wave shielding ink comprising two or more ink lines each of which has a width of L and crosses with each other to form a mesh and the film base material mounted with the pattern, and the area of the intersections of the ink lines each having a width of L is twice to 30 times as wide as L×L.
