ELECTROMAGNETIC SHIELDING SHEET AND METHOD FOR MANUFACTURING SAME

摘要

Blackened layers 23A and 23B are formed by depositing Cu—Co alloy particles on the surfaces of a metal layer 21. The metal layer 21 coated with the blackened layers 23A and 23B of the Cu—Co alloy particles is subjected to a chromating process to form density-intensifying layers 25A and 25B on the blackened layers 23A and 23B. A base 11 is laminated to the density-intensifying layer 25A or 25B. A conductive structure 109 consisting of the meal layer 21, the blackened layers 23A and 23B, and the density-intensifying layers 25A and 25B is processed by a photolithographic process to complete an electromagnetic shielding sheet 1 having a mesh conductive structure.
