Abstract
An aluminum electric wire (10) has a metallic core wire (11) coated with an insulation coating (13). A female terminal fitting (20) made of metal different from the core wire (11) has a wire barrel (25) to be connected to the aluminum electric wire (10). A solder seal (30) is formed of solder having a main component with an ionizing tendency close to that of the terminal fitting. The wire barrel (25) is crimped to the core wire (11) exposed by peeling off the insulation coating (13) of the aluminum electric wire (10) and partially sealed with the solder. A seal connection portion (14) connects the insulation coating (13), the exposed core wire (11) and the solder seal (30) to each other in a condition where the coating (13) and the solder seal (30) are sealed off from each other.
