Assignee: ASAHI KASEI MICRODEVICES CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 0:
1. A current sensor comprising:
at least one magnetoelectric conversion element;
a conductor which at least partially surrounds the at least one magnetoelectric conversion element in a plan view and through which a measurement current to be measured by the at least one magnetoelectric conversion element flows;
a signal processing IC which processes a signal output from the at least one magnetoelectric conversion element;
an IC supporting portion which supports the signal processing IC on a first surface;
an insulating element supporting portion which supports the at least one magnetoelectric conversion element on a surface on a same side as the first surface and is spaced apart from the IC supporting portion and the conductor;
an encapsulating portion which encapsulates the at least one magnetoelectric conversion element, the conductor, the signal processing IC, the IC supporting portion, and the insulating element supporting portion;
a pair of first lead terminals which is partially exposed outside the encapsulating portion and electrically connected to the conductor and which inputs the measurement current to the conductor and outputs the measurement current from the conductor;
a suspending pin which is (i) partially exposed outside the encapsulating portion, (ii) spaced apart from the conductor and the IC supporting portion, and (iii) electrically insulated from the conductor and the IC supporting portion; and
a plurality of second lead terminals which is exposed from a surface opposite to a surface of the encapsulating portion from which the pair of first lead terminals is exposed, wherein
the insulating element supporting portion further supports the suspending pin on the surface on the same side as the first surface,
the suspending pin is separate from the plurality of second lead terminals, and is exposed from a surface different from each of the surface of the encapsulating portion from which the pair of first lead terminals is exposed and the surface of the encapsulating portion from which the plurality of second lead terminals is exposed, and
at least one second lead terminal of the plurality of second lead terminals is electrically connected to the signal processing IC, and the suspending pin is not electrically connected to the signal processing IC.
