Title:

MAGNETIC SHIELD BODY FOR CURRENT SENSOR, AND CURRENT SENSOR DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/162687

Kind Code:

A1

Abstract:

In a first magnetic shield (20), second side surface portions (28a, 28b) of a second plate (22) are disposed so as to be perpendicular to first side surface portions (25a, 25b) of a first plate (21). As a result, the first magnetic shield (20) suppresses the intrusion of disturbance magnetic fields from a total of five directions, that is, one direction from a first-upper-surface-portion (24) side and the four directions of the first side surface portions (25a, 25b) and second side surface portions (28a, 28b). Meanwhile, in a second magnetic shield (30), a third upper surface portion (33) of a third plate (31) suppresses the intrusion of disturbance magnetic fields from the third-upper-surface-portion (33) side. Further, third side surface portions (34a, 34b) shield against disturbance magnetic fields from the same two directions as the first side surface portions (25a, 25b).
