Abstract
A resistor includes a resistive element, a first electrode, and a second electrode. The first electrode is disposed at a gap from the second electrode. The first electrode and the second electrode each have a top surface and a bottom surface. The resistive element is arranged so as to span from the first electrode to the second electrode on the top surface side, and is welded to the first electrode and the second electrode. Weld junctions that are formed by welding the resistive element to the first electrode and the second electrode, respectively, are formed diagonally such that the width thereof in the direction in which the first electrode and the second electrode face each other decreases from the top surface to the bottom surface.
