Title:
ELECTRICAL CURRENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/039264
Kind Code:
A1
Abstract:
In the present invention, a magnetic sensor chip (140) comprises at least one magnetic sensor having a magnetoresistance element and a plurality of connection terminals (142-145) connected electrically to the at least one magnetic sensor. A plurality of signal terminals (151-154) are separate from a current path (110) and are connected electrically to the plurality of connection terminals (142-145) by bonding wires (180). A support body (160) is separate from the current path (110), has a potential different from that of the current path (110), and supports the magnetic sensor chip (140). The at least one magnetic sensor is disposed at a position overlapping the current path (110) when observed from a direction in which the magnetic sensor chip (140) and the support body (160) are positioned in a row.
