PROBLEM TO BE SOLVED: To provide an electrical connection component capable of maintaining a low contact resistance over a long period.SOLUTION: An electrical connection component 1 is used by bringing a first contact part 33 provided in a first component 3 into contact with a second contact 23 provided in a second component 2. The first contact 33 has a first base metal 31 composed of a metal, and a first CuSn alloy layer 32 existing on the first base metal 31, and has a substantially spherical shape bulged out to the second contact 23 side. The second contact 23 has a second base metal 21 composed of a metal, and a second CuSn alloy layer 22 existing on the second base metal 21, and has a substantially tubular shape. The radius of curvature r (mm) of the first contact 33, and the contact load F(N) in a state where the first CuSn alloy layer 32 and the second CuSn alloy layer 22 are abutting, satisfy the following formulae (1) and (2); Fr≥0.8 ... (1), F≤5 ...(2).SELECTED DRAWING: Figure 2 |
