ABSTRACT:
In a current sensor having a magnetic gap, a main body is divided into a first case segment having a terminal and a second case segment. An opening is formed in the main body. A magnetic sensor element is mounted on an element mounting portion arranged on a surface of the first case segment, the surface attaching to the second case segment. The sensor element is electrically coupled with the terminal. A core holding portion is formed in the main body that surrounds the opening and the element mounting portion. A core having the magnetic gap is inserted in the core holding portion. The sensor element is arranged in the magnetic gap of the core on the element mounting portion. The sensor element can thereby be disposed accurately in the magnetic gap of the core, and detection accuracy of the current sensor can be increased.
