Abstract
An object of the invention is to improve electrical connection performance by increasing a pressure of contact between an electric wire and a terminal. A conductor press bond part () of a terminal is formed in substantially a U-shaped cross section opened upward by a base plate (A) and a pair of conductor crimp pieces (B,B) extended upward from both right and left lateral edges of the base plate (A). A range from the base plate (A) to the root of the pair of conductor crimp pieces (B,B) is formed as a curved wall (H) with substantially a circular arc shape, and when a radius of curvature of an inner surface of the curved wall (H) is R and a radius of a conductor of the electric wire is r, the curved wall is set so as to satisfy R<r. In the case of pressing and bonding this terminal to the electric wire, the conductor (Wa) of the electric wire is inserted between the pair of conductor crimp pieces (B,B) and by a press bond operation of a lower mold () and an upper mold () of a press bond device in its insertion state, the pair of conductor crimp pieces (B,B) is inward rounded to be crimped so as to wrap the conductor (Wa) with the base plate (A).
