Title:
CURRENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/185964
Kind Code:
A1
Abstract:
This current sensor (1) is provided with: a conductor (10) in which a current to be measured flows; and two magnetic sensors (21, 22). The conductor is provided with: a first flow channel (11); a second flow channel (12) parallel with the first flow channel in the width direction (X) of the first flow channel; and a first connecting part (13) at which the first flow channel and the second flow channel are merged. The two magnetic sensors are disposed parallel in the width direction, and detect magnetic fields (H1, H2) generated by the current that flows through the conductor. In the conductor, a first notch part (16) is provided by cutting out a side edge which, among both side edges of the first flow channel, is farther from the second flow channel in the width direction. Among the two magnetic sensors, a first magnetic sensor (21) disposed closer to the first flow channel than to the second flow channel is positioned near the side edge which, in the first flow channel, is on the side opposite the first notch part.
