Abstract:
A busbar (110) includes: a section to be measured; and a frame section (170) surrounding the section to be measured and having an insulation sheet (160) fixed thereto. The frame section (170) includes a counter frame section (172) facing a plurality of signal terminals as viewed from the direction in which the busbar (110) and the plurality of signal terminals are arrayed. In the portion of the frame section (170) other than the counter frame section (172), a gap (175) that hinders the flow of a current (I) to be measured is provided. The insulation sheet (160) covers the section to be measured and at least a portion of the frame section (170) as viewed from the direction in which the busbar (110) and the insulation sheet (160) are arrayed. The edge (162c) of the insulation sheet (160) on the side of the plurality of signal terminals in the direction in which the busbar (110) and the plurality of signal terminals are arrayed is located at the edge (172c) of the counter frame section (170) on the side of the plurality of signal terminals or at a position remoter from the plurality of signal terminals than the edge (172c) of the counter frame section (172) on the side of the plurality of signal terminals.
