The wire insulator pressure-cut connector terminal comprises a base plate formed integral with at least one cutter plate portion with a cutting open slot and a first terminal contact end portion, and a terminal box formed integral with a partially U-shaped section housing portion for housing the base plate and a second terminal contact end portion for constructing a female terminal contact end portion in cooperation with the first terminal contact end portion of the base plate. Since the base plate formed with the cutter plate portion and the terminal box formed with the terminal contact end portion are made of different materials with different thicknesses, respectively, it is possible to freely provide a sufficient rigidness for the cutter plate and a preferable elasticity for the terminal contact end, independently, according to the diameter and the material of the wire insulator.
