Abstract
The terminal of the lead portion of the sheathed electric wire having a resin sheath thereon is connected to the terminal fitting in the connector body 11, and a wire leading part 14 formed of a resin having a wire receiving groove 15 for receiving the terminal of the sheathed electric wire 23 is extending from the connector body 11. The wire leading part 14 and the resin sheath 25 of the sheathed electric wire 23 are heat-welded in the state that the cross sectional configurations of the wire receiving groove 15 and the sheathed electric wire 23 are selected to be the same rectangular shape. Since both resin members are uniformly kept in contact with each other in the stage before heat welding is applied, both resin members are welded surely and uniformly so that a waterproof ability may be enhanced.
