ABSTRACT:
A method for manufacturing rectangular plate type chip resistors and a rectangular plate type chip resistor obtained by this method. The method includes the steps of (A) providing a resistive alloy plate strip of predetermined width and thickness, (B) forming an insulating protective film of a predetermined width longitudinally along the middle of upper and lower faces of the alloy plate strip, (C) forming an electrode layer composed of integrated surface, back, and end electrodes, along both sides of the protective film by electroplating, and (D) cutting the alloy plate strip coated with the protective films and the electrode layers in step (C) transversely in predetermined lengths, wherein resistance is controlled to be within a predetermined range by adjusting the thickness of the alloy plate strip in step (A), the width of the protective film formed in step (B), and the cutting length in step (D).
