PROBLEM TO BE SOLVED: To provide a design method capable of clarifying specifications of materials which can be changed without the need of trial production evaluation or the like at the time of correspondence for thinning of terminals with wire crimping parts of the same shapes. SOLUTION: A reinforcedαbrass material is used for manufacturing a terminal with a wire crimping part, and when a 0.2% yield strength of a non-reinforcedαbrass material (I) conventionally used isσ<SB>0.2-I</SB>(MPa), and a plate thickness is t<SB>I</SB>(mm), a reinforcedαbrass material (F) satisfying a constant relation between a 0.2% yield-strengthσ<SB>0.2-F</SB>(MPa) and a plate thickness t<SB>F</SB>(mm) is selected. Then, the reinforcedαbrass material used is to be composed of copper by 62 to 71.5 wt.% and the rest of zinc, and a crystal particle size is to be aligned at 1 to 2μm, and the 0.2% yield strength to be 300 to 700 MPa.
