Abstract: Provided is a current sensing resistor including a plate-shaped resistive element containing a resistive material, and plate-shaped electrodes joined to opposite sides of the plate-shaped resistive element, each plate-shaped electrode containing an electrode material. Each electrode includes an upper electrode portion that is substantially flush with the resistive element, a lower electrode portion to be mounted on a wire pattern, and a step portion located between the upper electrode portion and the lower electrode portion. The upper electrode portion is wider than the resistive element and the lower electrode portion in the direction orthogonal to the direction in which the electrodes are arranged.
