Abstract
The present invention relates a shunt resistor and a shunt resistance device. The shunt resistor (1) includes an electrode member (10). The electrode member (10) includes a contact portion (10a) contacting a resistance element (5), and a slit (20) formed on the contact portion (10a).
Claims7
A shunt resistor comprising an electrode member made of a conductive material, an electrode, and a resistance element,
- wherein the resistance element has a plate shape with thickness, and has a first resistance element surface and a second resistance element surface opposite to the first resistance element surface in a thickness direction,
- wherein the electrode member has a contact portion configured to contact the resistance element,
- wherein the contact portion has a first surface adjacent to the resistance element and a second surface opposite to the first surface,
- wherein the contact portion, the resistance element, and the electrode are laminated in the thickness direction, so that the first surface is connected to the first resistance element surface, and the electrode is connected to the second resistance element surface, and
- wherein the electrode member comprising:
- a slit formed on the contact portion.
