An object of the present invention is to provide an electrical terminal (10) having a simple structure connecting metal materials unsuitable as electrical terminal materials together. The electrical terminal (10) has a contact (20) and a coupling member (30). The contact (20) has a shape extending frontward and rearward. The contact (20) is made of a metal material unsuitable as an electrical terminal in itself, such as alumel or chromel. The coupling member (30) is fixed to the contact (20) by spot welding or the like. The coupling member (30) is made of a metal suitable as an electrical terminal material, such as a copper alloy. The coupling member (30) has an insertion opening (31), a spring portion (32), and a crimping portion (33). Through the insertion opening (31), a contact made of the same material of a mating electrical terminal is inserted. The mating contact inserted through the insertion opening (31) is pressed against the contact (20) by the spring portion (32). Also, the crimping portion (33) is crimped so that a core (51) of a compensating lead wire (50) is pressed into contact with the contact (20). |
