Abstract
The invention forms a Sn coating layer and a Cu—Sn alloy coating layer having a suitably controllable planar shape in a PCB terminal. A group of Sn coating layers being as a plurality of essentially parallel lines is formed as the surface coating layer, and a Cu—Sn alloy coating layeris exposed on the outermost surface on both sides of Sn coating layers each constituting the group of Sn coating layers. The Sn coating layers have a width of 1 to 500 μm, an interval between adjacent Sn coating layers is 1 to 20000 μm, and an outermost maximum height roughness in a terminal insertion direction is at most 10 μm.
