ABSTRACT:
A protective member (28) having a melting point lower than a cover (12) is provided on a distal end of a protrusion (22) of the cover (12). A terminal (13) and a covered electric wire (19) are housed in a groove portion (18) of a connector housing (11), and the protrusion (22) of the cover (12) is inserted into the groove portion (18), and thereafter, an ultrasonic vibration is applied to the covered electric wire (19) and the terminal (13) from the cover (12). A covering portion (27) of the covered electric wire (19) is melted and removed by the ultrasonic vibration. The protective member (28) absorbs a heat generated in the cover (12) by applying the ultrasonic vibration, and is preferentially melted. Therefore, the protrusion (22) is not deformed due to the heat, so that a contact area of a core wire (26) and the terminal (13) can be secured.
