1. A shunt resistor comprising:
a first resistive body;
two base materials sandwiching the first resistive body therebetween and joined to the first resistive body by welding;
the first resistive body being orthogonal to a longitudinal direction of the two base materials such that a height direction of the first resistive body is orthogonal to the longitudinal direction of the two base materials;
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 being placed on an upper surface or a lower surface of the first resistive body so as to be orthogonal to the first resistive body, and being placed at a central position in the height direction of the first resistive body, and parts of the second resistive body in contact with the two base materials being joined to the two base materials by welding.
