Abstract
A straight angle conductoris provided with a cladding material including a core-sheet metaland conductor-sheet metalsthat sandwich both surfaces of the core-sheet metal. The conductor-sheet metalshaving a volume resistivity equal to or less than 5.0 (μΩ·cm) wraps both sides of the core-sheet metalhaving a thermal expansion coefficient equal to or less than 10 (×10/C. °) to prevent the core-sheet metalfrom being exposed to an outside of the conductor-sheet metals. As a result, it prevents occurrence of an electrical potential difference in a boundary side face between the core-sheet metaland the conductor-sheet metalsto improve corrosion resistance. Especially even when the straight angle conductoris used on a silicon crystal wafer for a solar cell, damage of the silicon crystal wafer caused by heat occurring in soldering process of the conductoror a change in temperature on use thereof for a solar cell is avoided.
