ABSTRACT:
A terminal is placed in a groove portion of a first member and, in a state where a covered electric wire is placed on the terminal, the resulting laminate is pressed by a second member. By applying ultrasonic vibrations while this pressing is being maintained as is, the first member and the second member are welded to each other. The second member is made of resin having a heat resistance lower than the resin constituting a block portion which forms a bottom wall portion of the groove portion. By performing the above pressing in a state where heat is being generated by application of ultrasonic vibration, it does not happen that the block portion supporting the terminal is recessed even when the second member is recessed. This eliminates the possibility that the terminal may be embedded in the resin.
