<p>PROBLEM TO BE SOLVED: To provide a coated body which is low in production cost and has excellent corrosion resistance.SOLUTION: A coated body 10 is to be arranged on a conductor 20, and the conductor 20 contains at least one of copper, silver and their alloys. The coated body 10 comprises, from the side of the conductor 20, a first layer 12 containing palladium; and a second layer 14 containing gold. The first layer 12 is in direct contact with the conductor 20 and has a first area 31 and a second area 32 arranged on the side of the second layer 14 relative to the first area 31. The second area 32 is higher in phosphorus concentration than the first area 31. The first layer 12 has, from the side of the conductor 20, an inner side layer 16 including the first area 31 and an outer side layer 18 including the second area 32, and the outer side layer 18 has a phosphorus concentration of 0.05 mass% or higher.</p> |
