There is provided a method for manufacturing rectangular plate type chip resistors which provides easy and convenient control of resistance, and easy and low cost manufacture of rectangular plate type chip resistors having a reliable electrode structure, as well as a rectangular plate type chip resistor obtained by this method and having excellent properties particularly at low resistance. The method includes the steps of (A) providing a resistive alloy plate strip 10 of predetermined width and thickness, (B) forming an insulating protective film (11a, 11b) of a predetermined width longitudinally along the middle of upper and lower faces of the alloy plate strip, (C) forming an electrode layer 12 composed of integrated surface, back, and end electrodes (12a, 12c, 12b, respectively), 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).
