Abstract
To manufacture an electromagnetic-wave shielding and light transmitting plate having a conductive pattern of which line width is narrow and open area ratio is high, a negative pattern 2 composed of dots is printed on a transparent film 1 having a high affinity for a plated layer of a conductive material by using a transparent resin having a low affinity for the plated layer and a backside coating layer 3 is formed by printing a transparent resin on the entire back surface of the transparent film 1. Then, a conductive material layer is formed by electroless plating to cover the film exposed surface not covered by the negative pattern 2 of the film 1, thereby forming the conductive pattern 4. After that, the blackening treatment is conducted, thereby obtaining the electromagnetic-wave shielding and light transmitting plate.
