A connector terminal which can achieve high mechanical connection strength and stabilized low electrical connection resistance when it is crimped to an aluminum electric wire, and in addition, can suppress electrical contact resistance low when it is fitted to a mating connector terminal is provided. In a connector terminal (1A) having an electrical contact section (10) which is brought into contact and conducted with a mating connector terminal by fitting to the mating connector terminal, and a conductor crimping section (12) which is crimped to the conductor of an electric wire, a metal material which constitutes the terminal uses aluminum or an aluminum alloy as a base material (100), a Zn layer (101) having a thickness in the range from 0.1μm to 2.0μm by electroless plating and a Cu layer (102) having a thickness in the range from 0.5μm to 1.0μm by electrolytic plating are formed in sequence on the surface of the base material (100), and an Sn layer (105) having a thickness in the range from 0.7μm to 1.7μm by electrolytic plating is formed on the outermost surface. |
