Claim:
A terminal for an engaging type connector comprising: a punched Cu alloy strip serving as a base material and having an arithmetic mean roughness Ra of 0.15 μm or above with respect to one direction and an arithmetic mean roughness Ra of 4.0 μm or below with respect to all directions; and a coating formed on the base material by postplating processes and including a Cu—Sn alloy layer and a Sn layer; wherein the Cu—Sn alloy layer is 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 a part of the Sn layer on the solder-bonding part has a mean thickness greater than that of a part of the Sn layer on the engaging part.
