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.
