Reactor

摘要

A reactor includes a coil, a magnetosensitive element attached to a lead wire of the coil, a magnetic shielding plate that shields the magnetosensitive element from a magnetic field of the coil, and a case body in which the magnetic shielding plate, the magnetosensitive element and the coil are housed. In the reactor, the magnetosensitive element and the coil are covered with a resin containing a magnetic material in the case.

1. A reactor comprising:
a coil; a core of the coil; a magnetosensitive element attached to a lead wire of the coil; a magnetic shielding plate that (i) is disposed between the core of the coil and the magnetosensitive element and (ii) shields the magnetosensitive element from a magnetic field of the coil, wherein the magnetic shielding plate is shaped as a box; a case in which the magnetic shielding plate, the magnetosensitive element and the coil are housed, wherein the magnetic shielding plate is within the case; and a resin containing a magnetic material is filled in both (i) a first region of the case surrounded by the magnetic shielding plate and (ii) a second region of the case that includes the coil, wherein the resin containing the magnetic material filled in the first region of the case forms a core of the magnetosensitive element, wherein the magnetosensitive element and the coil are covered with the resin containing the magnetic material in the case.
