Abstract: The present invention relates to a jumper element, a shunt resistor apparatus, and a method of adjusting characteristic of a shunt resistor apparatus for current detection. The jumper element (10) for constituting the shunt resistor apparatus for current detection is made of conductive metal material. The jumper element (10) includes: a body structure (11) that can be coupled to a resistance element (5) constituting a part of the shunt resistor apparatus; and a protrusion (12) formed on a side portion of the body structure (11), wherein the protrusion (12) is located so as not to overlap the resistor element (5).

Abstract: The mounting area for an electronic component and a resistor for current detection is reduced. A current detection resistor for detecting current includes a plate-like resistive body, and a first electrode and an opposite second electrode which are stacked in a thickness direction of the resistive body and are disposed so as to sandwich the resistive body. The first electrode has a groove portion.
