Abstract
A shunt resistor the resistive value of which can be lowered simply and easily has: a first resistive body, two base materials that sandwich the first resistive body therebetween and are joined by a welding to the first resistive body, and a second resistive body joined by a welding to the two base materials at different positions from the first resistive body. In addition, the second resistive body can come into contact with the first resistive body.
Claims1
A shunt resistor comprising:
- a rectangular first resistive body;
- two rectangular base materials sandwiching the first resistive body therebetween and joined to the first resistive body by welding;
- a second resistive body joined to the two base materials by welding at a position different from the first resistive body;
- and
- the second resistive body is formed in a downward U shape in plan view, having an upper surface thereof flush with upper surfaces of the two base materials and having a lower side surface thereof joined to upper side surfaces of the two base materials by welding, thereby, the second resistive body being joined to the two base materials on adjacent positions to the first resistive body but are in a non-contact state.
