摘要： The present invention relates to a magnetic sensor and a magnetic detecting method of the same capable of detecting at least a magnetic field perpendicular to a substrate and a magnetic field parallel to the substrate in a state where the respective magnetic field components are mixed. One embodiment of the magnetic sensor detects a magnetic field of the orthogonal three axes, and includes a magnetic detector including a magnetic field sensitive material configured to detect a magnetic field component in a first direction, a magnetic field direction converters configured to convert a magnetic field component in a second direction and a magnetic field component in a third direction into magnetic field components in the first direction, the second direction being perpendicular to the first direction, the third direction being perpendicular to both of the first and the second directions.

摘要： A current sensor is configured such that at least one magnetoelectric conversion element, a conductor, and a signal processing IC are encapsulated with an encapsulating portion. The current sensor is comprised of a pair of first lead terminals that is partially exposed on a side surface of the encapsulating portion, is electrically connected to the conductor, inputs a measurement current to the conductor, and outputs the measurement current from the conductor; a metal member that is partially exposed on a side surface of the encapsulating portion and is spaced apart from the conductor; and an element supporting portion that is comprised of a metal plate or a semiconductor substrate, supports the at least one magnetoelectric conversion element and a metal member on a surface on a same side as the first surface, and is spaced apart from the conductor.
