PURPOSE:To enable the direct connection of a mother board and matrix circuit board to each other without using through-holes and stereoscopic printing circuit with a matrix circuit board by using metallic conductor wires of which insulating parts exposed as pins for connecting at least in two directions on the flank. CONSTITUTION:The spacings among three-dimensional wirings 14 of a plain network type are impregnated with an insulating material 3 and are simultaneously adhered to a supporting plate 2 to form the circuit board. The insulating parts to mount electric parts, etc., of the wirings 11 and wirings 12 exposed on the surface are removed to expose the metallic conductor wires when viewed in the plane of the insulation coated metallic conductor wires 1 stereoscopically wired in a network form. Monochromatic LED chips 4 are then adhered via solder to the wirings 11 and the wirings 12. The insulating parts to mount the electric parts, etc., of the wirings 11 and 12 and to constitute bonding pads are similarly removed to expose the metallic conductor wires and LED pair chipes 6, are adhered via solder to the wirings 11 and are connected by bonding pads 5 provided on the wirings 12 and the wires 7. |
