Document Type and Number:
WIPO Patent Application WO/2023/276673
Kind Code:
A1
Abstract:
In this invention, a body (111) has, on an end surface (111e), a notch part (112) that is recessed in a direction away from a plurality of signal terminals (170) in a first direction. The notch part (112) has a busbar (110) passing therethrough in a third direction. A first magnetic detection element (120) is positioned above the busbar (110) in the third direction. A second magnetic detection element (130) is positioned inside the notch part (112) and below the center (C) of the busbar (110) in the third direction. The first magnetic detection element (120) detects a magnetic field component oriented toward one side in the first direction within a magnetic field (e) generated by an electric current (I) flowing through the body (111). The second magnetic detection element (130) detects a magnetic field component oriented toward the other side in the first direction within the magnetic field (e) generated by the electric current (I) flowing through the body (111).
