<p><P>PROBLEM TO BE SOLVED: To provide a new electromagnetic wave shielding sheet manufacturing method in a dry procedure, capable of inline production. <P>SOLUTION: An electromagnetic wave shielding material manufacturing method comprises the first step of collecting a laser beam onto a conductive sheet constituted by forming a conductive layer comprising a conductive substance on a first base, removing the conductive layer, and forming a conductive pattern; and the second step of filling a portion between the conductive patterns with resin. In the electromagnetic wave shielding material manufacturing method, the first base is subjected to a peeling process. In the electromagnetic wave shielding material manufacturing method, the peeling process is an adhesive process in which adhesiveness is eliminated using an energy beam. In the electromagnetic wave shielding material manufacturing method, the second step is the step of crimping the conductive sheet on which the conductive pattern is formed onto a sheet in which a resin layer is formed on a second base. The electromagnetic wave shielding material manufacturing method further comprises the third step of peeling the first base off after the second step. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
