Abstract

A manufacturing method of flattening resistor (1), comprising: - disposing a substrate (10); - forming by printing an electrode layer (20) on both ends of the substrate (10); - forming by trimming a tangential concave platform (50) by laser-cutting or grinding a surface of the electrode layer (20); - forming by sputtering a resistive layer (30) covering the tangential concave platform (50) of the electrode layer (20); and - forming by printing a protective layer (40) on the resistive layer (30). The application further discloses a flat resistor obtained by the method. The present disclosure solves the problems of increased impedance and abnormal product characteristics caused by improper jointing of the interface between the electrode layer and the resistive layer, which includes using laser-cutting or grinding to eliminate the step difference of the interface and process the discontinuous structure of the electrode layer after the electrode layer process is completed.
