覆させても問題はない。As described above, since it is covered with the insulating resin film 30 and held in a thin rectangular shape, the insulating plate 11
Unnecessary portions can be cut off before being fixed on the upper side, and a required circuit can be formed from the vertical and horizontal conductors 13 and 14. After that, as shown in FIG.
The wiring board 10 is manufactured by mounting and fixing on the substrate 1 and making a pressure contact connection with the pressure contact terminal 15 as shown in FIG. At the time of connection of the press contact terminal 15, since the covered resin film 30 is broken and connected to the conductor by pressure, there is no problem even if the insulating film 30 is covered.

を設ける必要がなくなる。As is apparent from the above description, according to the present invention, the insulation circuit for supporting the electric wire in the electric circuit using the electric wire and the press contact terminal for press-connecting the electric wire as the internal circuit of the electric connection box. The plate can be formed in a flat plate shape without being caught by the circuit. Therefore, there is no need to provide an insulating plate with a complicated shape required in the case of the conventional pressure welding method,
Cost can be reduced. In addition, since the electric wire to be wired on the insulating plate may be a straight wire having a certain length and parallel wiring at a required pitch, the wiring work of the electric wire is facilitated, and the processing speed can be increased, and the processing is complicated and effective. There is no need to provide equipment.
