Abstract: An insulation-displacement terminal has opposed side walls (12) and a wire-receiving space therebetween. V-shaped insulation-displacement portions (16) are formed by a pair of plates (16F, 16R) that are bent from the side walls (12) and project into the wire-receiving space. A bending angle (&bgr;) between one plate (16R) and the side wall (12) is larger than a bending angle (&agr;) between the other plate (16F) and the side wall (12). A pulling force on the wire (W) does not make a loose movement since the bending angle of the plate (16F) located at the side behind with respect to a pulling direction is a right angle. Further, since the bending angle (&bgr;) between the plate (16R) and the side wall 12 is larger, an angle (&ggr;) between the plates (16F) and (16R) of the insulation-displacement portion (16) is sufficiently large to ensure a wide contact area with a core (Wb) of the wire (W). Thus, a high contact reliability can be secured.
