1. A plate shunt resistor used in current detection comprising:
a resistance element; and
a pair of electrodes connected to both ends of the resistance element in a first direction,
wherein the shunt resistor comprises:
a first side surface disposed on a first side of the shunt resistor and extending parallel to the first direction,
a second side surface disposed on a second side of the shunt resistor and extending parallel to the first direction, the second side being opposite to the first side of the shunt resistor,
a projecting portion formed on the first side surface of the shunt resistor and projecting in a second direction perpendicular to the first direction, and
a recessed portion formed on the second side surface of the shunt resistor and recessed in the second direction,
wherein the projecting portion has a portion of the resistance element and portions of the pair of electrodes, and
wherein a bottom of the recessed portion is defined by a side surface of the resistance element parallel to the first direction.
