Abstract
A terminal for an engaging type connector includes a punched Cu alloy strip as a base material, a coating formed on the Cu alloy strip by postplating processes and including a Sn layer, and a Cu—Sn alloy layer sandwiched between the base material and the Sn layer. The Sn layer is smoothed by a reflowing process. The terminal has an engaging part and a solder-bonding part, and the surface of a part of the base material corresponding to the engaging part has a surface roughness higher than that of the surface of the base material corresponding to the solder-bonding part. The engaging part has a low frictional property and the solder-bonding part has improved solder wettability.
