Abstract: The present invention provides a method for manufacturing a conductive film, comprising the steps of: applying, to a substrate, a conductive paste dispersed in an organic material and comprising metal particles and Fe—B—Cu—C alloy magnetic heating element particles; and selectively sintering the applied conductive paste by means of induction heating so as to form a conductive film, wherein the magnetic heating element particles are implemented with crystallized Fe—B—Cu—C alloy particles. Therefore, it is possible to selectively form a conductive adhesive layer by sintering through induction heating. In addition, it is possible to produce an adhesive capable of low-temperature bonding by forming a magnetic heating element having crystal grains with a large coercive force through heat treatment after formation of an alloy.

Abstract: The present invention comprises the steps of: applying, on a substrate, a conductive paste including metal particles that are dispersed in an organic material and have a first particle diameter, and a magnetic heating element that has a second particle diameter; and selectively sintering the applied conductive paste by induction heating to form a conductive film, wherein the magnetic heating element may be contained in an amount of 10-50 wt% with respect to the metal particles. Therefore, a conductive adhesive layer can be selectively formed by performing the sintering through induction heating. In addition, by adding a small amount of the magnetic heating element to conductive metal powder having a low melting point, low-temperature bonding and electric conductivity can be simultaneously attained.
