PURPOSE:To form an encoding plate of a long life at a low cost by pressing a metallic plate to form conductive patterns, and forming these into one body with a synthetic resin. CONSTITUTION:A metallic plate like a flat plate such as spring type phosphor bronze plate is pressed to louver part form a root part 5a, thereby forming projecting conductor patterns 5b and a common conductor pattern 5c. A synthetic resin 6 is molded to this plate 5, whereby an encoding plate 1 is made. |
