い。In the connection structure of the crimp terminal and the electric wire according to claim 2 which are connected by the method according to claim 1,
Since a heat dissipation sheet with good thermal conductivity is attached to the outer peripheral surface of the core wire barrel of the crimp terminal that is connected to the core wire of the electric wire,
The heat locally generated in the electrical connection portion can be conducted to the outside through the heat radiation sheet from the opening side of the terminal accommodating chamber.

Therefore, it does not interfere with the insertion of the crimp terminal. Therefore, since the heat dissipation area is increased and the heat dissipation effect is increased, even if the heat dissipation sheet is enlarged, it can be inserted into the terminal accommodating chamber due to bending.
