1. A current detecting apparatus comprising:
a plate-like bus bar; and
a magnetic sensor including a main body that measures a current flowing through the bus bar and terminals extending individually from the two opposing sides of the main body, and wherein:
the terminals include a signal terminal that outputs a detection signal and a supply terminal that supplies electric power to the main body,
the signal terminal and the supply terminal extend from the main body,
the main body includes a portion overlapping the bus bar and a portion not overlapping the bus bar as viewed along a thickness direction of the bus bar, and
the signal terminal and the supply terminal extend from the portion of the main body not overlapping the bus bar without overlapping the bus bar; and
two plate-like magnetic shields having a same shape and same size disposed away from each other so as to sandwich the bus bar and the magnetic sensor in the thickness direction, and wherein:
the two plate-like magnetic shields are disposed parallel to the bus bar and overlapped so as not to extend off from each other as viewed along the thickness direction, and
as viewed along the thickness direction, the main body and the two magnetic shields are disposed so that plane centers are aligned with each other, and the plane center of the main body is located on a widthwise end face of the bus bar.
