<P>PROBLEM TO BE SOLVED: To provide an ultrasonic joining method for suppressing production of a burr while suppressing degradation of strength. <P>SOLUTION: The ultrasonic joining method for performing ultrasonic joining of a conductor part 41 exposed by removing the coating of an electric wire 40 to a terminal 50 includes: a first step of holding the conductor part 41 of the electric wire 40 and the terminal 50 between an anvil 32 and a horn 31 in which a recessed part is formed; and a second step of performing the ultrasonic joining by applying the ultrasonic vibration to the conductor part 41 of the electric wire 40 and the terminal 50 which are held in the first step. Further, in the first step, the conductor part 41 is received by the recessed part having a space area of 0.89-1.46 times as large as the cross-sectional area of the conductor part 41 of the electric wire 40. <P>COPYRIGHT: (C)2013,JPO&INPIT |
