摘要:
An electric current sensor includes: a core having a ring shape and including a plurality of core pieces, which are laminated and integrated to provide the core; a magnetic gap disposed on a predetermined part of the core; a Hall element disposed in the magnetic gap; a body for accommodating the core and the Hall element; and a seal member for sealing the core and the Hall element into the body. Each core piece has a thin plate shape, and the core includes deformation preventing means for preventing a deformation of the magnetic gap.
