An electric wire and crimp terminal arrangement comprising an electric wire and a crimp terminal of an open barrel type adapted to fix, by crimping to the electric wire , the crimp terminal comprising: an F-type crimp portion comprising a first and a second barrel tab , the first and the second barrel tab being disposed at opposite locations, with a longitudinal centerline of the electric wire to be crimped in between, the first and the second barrel tab having an identical length; and a C-type crimp portion ; the C-type crimp portion comprising a third barrel tab adapted to crimp the electric wire , the C-type crimp portion being configured to have the third barrel tab wrapped in a C-form on an outer periphery of the electric wire to be crimped, the F-type crimp portion is configured to have distal ends of the first and the second barrel tab put together to push into a tip end of the electric wire to be crimped; and the F-type crimp portion comprises a convex provided at a part thereof for the electric wire to be brought into contact therewith; characterized in that the electric wire that is crimped by the F-type crimp portion and the C-type crimp portion comprises a complex stranded wire involving a set of conductor element wires wound on an outer periphery of a reinforcement wire , the reinforcement wire having a strength greater than strengths of the conductor element wires of the set such that, after crimping operation of the F-type crimp portion , each of the conductor element wires of the set is compressed and gripped between the F-type crimp portion and the reinforcement wire ; and the convex having a height thereof set to be equal to or greater than one sixth of a diameter of the complex stranded wire . an F-type crimp portion comprising a first and a second barrel tab , the first and the second barrel tab being disposed at opposite locations, with a longitudinal centerline of the electric wire to be crimped in between, the first and the second barrel tab having an identical length; and a C-type crimp portion ; the C-type crimp portion comprising a third barrel tab adapted to crimp the electric wire , the C-type crimp portion being configured to have the third barrel tab wrapped in a C-form on an outer periphery of the electric wire to be crimped, the F-type crimp portion is configured to have distal ends of the first and the second barrel tab put together to push into a tip end of the electric wire to be crimped; and the F-type crimp portion comprises a convex provided at a part thereof for the electric wire to be brought into contact therewith; characterized in that the electric wire that is crimped by the F-type crimp portion and the C-type crimp portion comprises a complex stranded wire involving a set of conductor element wires wound on an outer periphery of a reinforcement wire , the reinforcement wire having a strength greater than strengths of the conductor element wires of the set such that, after crimping operation of the F-type crimp portion , each of the conductor element wires of the set is compressed and gripped between the F-type crimp portion and the reinforcement wire ; and the convex having a height thereof set to be equal to or greater than one sixth of a diameter of the complex stranded wire . <EOS>
