Abstract:
An electrically conductive material for a connection component is disclosed. The electrically conductive material includes a Cu—Sn alloy coating layer 5 in which a Cu content is 55 to 70 at % and has an average thickness of 0.1 to 3.0 μm, and a Sn coating layer 6 having an average thickness of 0.2 to 5.0 μm, which are formed in this order on a surface of a base material made of a copper or copper alloy sheet strip. When a reflected electron image of a material surface is observed with a scanning electron microscope at a magnification of 100 times, a region A and a region B having a higher brightness than the region A and in which the Cu—Sn alloy coating layer is not exposed coexist on the material surface, and an area ratio of the region A on the material surface is 2 to 65%.

Claim (Index 1):
An electrically conductive material, comprising:\n coating layers comprising a Cu\u2014Sn alloy coating layer and a Sn coating layer that is formed in sequence on a surface of a base material made of a copper or copper alloy sheet strip, wherein a Cu content in the Cu\u2014Sn alloy coating layer is from 55 to 70 at %, an average thickness of the Cu\u2014Sn alloy coating layer is from 0.1 to 3.0 \u03bcm, an average thickness of the Sn coating layer is from 0.2 to 5.0 \u03bcm, and a material surface of the electrically conductive material has an arithmetic mean roughness Ra in at least one direction of 0.15 \u03bcm or more and an arithmetic mean roughness Ra in all directions of 3.0 \u03bcm or less, and wherein when a reflected electron image of the material surface is observed with a scanning electron microscope at a magnification of 100 times, a region A and a region B having a higher brightness than the region A and in which the Cu\u2014Sn alloy coating layer is not exposed coexist on the material surface, and an area ratio of the region A on the material surface is from 2 to 65%, and wherein when the region A is observed with the scanning electron microscope at a magnification of 10,000 times, a region C covered with the Sn coating layer and a region D not covered with the Sn coating layer coexist in the region A, and an area ratio of the region C in the region A is from 20 to 70%.
