Abstract:
1. A method for manufacturing a printed-circuit board having an organic resin insulating layer and a metal wiring layer and having a film-like resistive element formed on the metal wiring layer thereof, the method comprising the steps in the following order: disposing a metal wiring layer on one surface of one organic resin insulating layer to form an organic resin printed-circuit board; forming a pair of electrodes on the metal wiring layer of the organic resin printed-circuit board; forming a film-like resistive element between the electrodes with resistive paste by a printing method such that the resistive paste overlaps the electrodes; applying a temperature and a pressure of a laminating press to the side of the metal wiring layer in the printed-circuit board without use of a laminating adhesive agent to change a resistance value of the film-like resistive element; trimming the film-like resistive element for adjusting the resistance value thereof; providing a circuit member having at least one layer of insulating layer; and laminating the circuit member with a layer of the organic resin printed-circuit board having the film-like resistive element formed thereon, inserting a laminating adhesive agent between the circuit member and the layer of the organic resin printed-circuit board.
