As described above, according to the present invention, the flat electric wire which has been crushed is bonded between the two insulating sheets with no gap and with a large contact area. Therefore, the thick electric wire is used. Even in this case, the adhesion of the electric wire to the sheet is improved, the electric wire is firmly fixed to the insulating sheet, and the deterioration of the insulating property due to the gap is prevented. Also, the contact area of the mating side such as the terminal is large, and the tip of the ultrasonic welding horn is also large area, so even if the welding horn has a small pressing force, it surely welds, thereby downsizing the welding machine. It is possible to reduce the equipment cost. Further, since the electric wire is crushed in the manufacturing process of the sheet circuit body, the crushing process can be performed in a short time without impairing the productivity.
