| abstract | (57) [Summary] (Modified) [Purpose] To improve the electrical conductivity by increasing the adhesion of jumper circuits, through-hole circuits, and electromagnetic wave shields to the circuit pattern, and to improve the bending resistance. [Structure] The circuit pattern 1 contains 3 or 4 kinds of indium, tin, lead and antimony, and the total content thereof is 0.02 to 0.15% by weight and the content of each is 0. Formed from a copper alloy rolled and annealed foil which has a bending resistance of 0.006% by weight or more and the balance of which is substantially copper, and has a conductivity comparable to that of pure copper. The electromagnetic wave shield 7 and the jumper circuit 6 are made of a conductive coating material which is surface-coated with titanate and contains metallic copper powder, a resol type phenol resin, a chelate layer forming agent, an adhesion improving agent, and a conductivity improving agent. The through-hole circuits 5a and 5b are composed of metal copper powder, resol-type phenol resin, whose surface is coated with titanate, It is formed of a conductive paint containing an amino compound and a chelate layer forming agent. |
