To provide a manufacturing method for an electric wire with a terminal by which elongation or getting thin of a core wire calked with a crimping piece of the terminal at the time of carrying out crimping connection of the terminal to the electric wire is prevented, breaking or coming-off of the electric wire is suppressed, and stable electric contact and adherence of the electric wire can be obtained.
The manufacturing method for the electric wire with the terminal relates to a method in which the electrically conductive terminal 20 is connected to the end of the electric wire 10, consisting of a core wire 12 made of electrically conductive strands and an insulation covering 14 covering the core wire 12. When the naked core wire 12 of the end of the electric wire is crimped on both sides with at least a pair of crimping pieces 26a and 26b in order to achieve the crimping connection, the crimping connection is carried out in the state that the axial elongation of a core wire end surface 12a of the core wire 12 in an axial direction of the core wire is regulated by making a core wire pressor 70 contact closely to the core wire end surface 12a.
