By stacking the films on top of each other and applying heat and pressure at the same time, the thermoplastic resin softens and develops adhesive properties, thereby firmly adhering the members to be adhered. Further, the conductive adhesive 56 applied to the terminal portion uses a thermoplastic resin modified with the thermosetting resin as a binder, and contains fillers of silver and carbon as appropriate to achieve sufficient conductivity. A film having strong adhesive properties similar to those described above can be formed. FIG. 11 is a circuit diagram showing the circuit configuration of the multi-row variable resistor. The resistors R and R' are connected to the resistor patterns 41 and 41' on the insulating substrate 4, and are connected to the terminals B to I.
The terminals J and L are connected to the terminal portions 43 and 43' of the insulating board.
are the terminal parts 44 and 45 of the insulating substrate 4, and the terminals K,
M corresponds to the terminal portions 44 and 45' of the insulating substrate 4, respectively.

As explained above, according to the present invention, when connecting the terminal portion of the insulating substrate and the terminal portion of the flat cable, the terminal portion of the insulating substrate and the terminal portion of the flat cable are brought into contact and heated and pressurized. ,
The conductive adhesive on the terminal and the adhesive in between create viscosity and firmly adhere to each other, eliminating the need for soldering work that requires skill and delicate conditions such as temperature and time, and eliminates the need for soldering. An excellent effect can be obtained in that the multi-row variable resistor can be made extremely thin and compact since there are no attached parts.
