PROBLEM TO BE SOLVED: To provide a production process of an electromagnetic shielding member having a reduced environmental load. SOLUTION: In a production process of an electromagnetic shielding member, a plastic substrate 1 is arranged below nozzles 3, and a mask 2 is arranged between the nozzles 3 and the plastic substrate 1 to cover the plastic substrate 1. The mask 2 is provided with a plurality of slits 2a extending in the direction of arrow A at an interval in the direction perpendicular to the arrow direction A. The nozzles 3 are moved in the direction of arrow A in Fig.1, and conductive powder 6 is sprayed from the nozzles 3. The conductive powder 6 thus sprayed passes through the slits 2a of the mask 2, collides against the surface of the plastic substrate 1 and is bonded onto the substrate 1 by collision energy. Subsequently, a mask 2A having slits extending in the different direction as compared with the mask 2 is used in place of the mask 2, and the conductive powder 6 is sprayed similarly. Consequently, conductive linear patterns 1a and 1b are formed on the surface of the substrate 1. COPYRIGHT: (C)2009,JPO&INPIT
