A material application apparatus 10 comprises a base 11 on which a workpiece W is placed, a syringe 13 that applies a material onto a movement track L, a movement structure 14 that moves the syringe 13 in three orthogonal axes directions, a rotation mechanism 15 that rotates the syringe 13 around the axis line of the syringe 13, and a control unit 17 that controls the movement structure 14 and the rotation mechanism 15 in accordance with a configuration of the track L. The syringe 13 includes a nozzle 19 provided to the front-end side of a main body 18 that contains a sealing agent or a material of resin used as an adhesive agent or the like. The discharge port 21 of the nozzle 19 is formed into a generally acute-angled triangle configuration to discharge the material so that a bead B having a sectional configuration in which the height is larger than 0.9 compared to the width of 1 can be formed. Also, the nozzle is adapted so as to be rotated in the periphery direction thereof by a motor M.

In a lead-free solder comprising an alloy composition composed mainly of tin, the alloy composition further contains 0.002 to 0.015% by mass of phosphorus. This lead-free solder can be used as a plating in a connection lead comprising: a copper strip or other strip conductor; and the plating provided on at least one side of the strip constructor, the plating having a shape such that the plating in the widthwise direction of the strip conductor has a bulge as viewed in section with the apex being located at a proper position in the widthwise direction of the strip conductor. By virtue of this constitution, the lead-free solder on its surface is less likely to be oxidized, and the connection lead has excellent bond strength owing to the property of the lead-free solder and, in addition, has the function of breaking the formed oxide layer and the function of removing included gas bubbles and can eliminate the need to form the plating in very large thickness. Further, the lead-free solder can be used as a connection element in an electrical component that is less likely to cause oxidation of the connection element on its surface and, thus, can have a strong connection structure by the connection element.
