A wire for use in robot including a conductor of metallic fiber-reinforced copper matrix composite whose plastic strain to rupture is substantially less than 0.2%. A plurality of conductors form a twisted wire (2). An insulation member (4) is coated on the twisted wire (2) to form a coated wire (6). The conductivity of the conductor is greater than 70% IACS and the tensile strength of the conductor is greater than 100 Kg/mm.sup.2. The metallic fiber-reinforced copper matrix composite is in-situ metallic fiber-reinforced copper matrix composite drawn with a total reduction in sectional area of 99.99% or more.
