<P>PROBLEM TO BE SOLVED: To provide an inexpensive and practical electromagnetic shielding member using aluminum which substantially eliminates contrast unevenness of a display screen by eliminating poor precision of an aluminum pattern formed by chemical etching when the material of a metal pattern is changed from copper to inexpensive aluminum. Ž<P>SOLUTION: In an electromagnetic shielding member where an aluminum mesh layer 2 is laminated on a transparent base 1, an oxide film 3 of aluminum at least on the upper surface of the aluminum mesh layer 2 (surface of the aluminum mesh layer 2 on the side remote for the transparent base) has a thickness of 0-13 Å, and a variation (Smax-Smin)/Sav in the opening area (S) of mesh is 0.059 or less. The Smax, Smin, and Sav represent the maximum value, minimum value and average value of the opening area (S), respectively. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
