The exposed conductor portion W1 is welded or adhered.
For this reason, the protruding terminal 210 is biased in a direction away from the wire connection fixing portion 50 by the elastic contact piece 33, so that the conductor portion W <b> 1 fixed to the wire connection fixing portion 50 does not easily interfere with the protruding terminal 210. Yes.
In addition, the conductor portion W1 is welded or adhered to the wire connection fixing portion 40 by an ultrasonic horn or the like, so that the conductor portion W1 is crushed toward the wire connection fixing portion 40. It is hard to interfere.

  The covering fixing part 60 is a so-called insulation barrel, and is crimped so that a pair of crimping pieces 61, 61 erected in a single piece from both side edges of the electric wire connection fixing part 40 covers the insulating covering part W <b> 2 of the electric wire W. It is a part to be done.

In such a connection structure 1 between an electric component and a terminal-attached electric wire, the size of the protruding terminal 210 in the protruding direction can be reduced by the size of the electric wire W overlapped with the protruding terminal 210.
