Document Type and Number:
WIPO Patent Application WO/2011/125431
Kind Code:
A1
Abstract:
Disclosed is a magnetic core (1) to be used in a current sensor, which is provided with a first open end plane (3a), which has a first element holding hole (5a) for holding a magnetoelectric conversion element (20) formed therein; and a second open end plane (3b), which has a second element holding hole (5b) for holding the magnetoelectric conversion element (20) formed therein, and which faces the first open end plane (3a). With such configuration, the magnetic core (1) can improve the detection sensitivity of the current sensor.
