  • Current sensor
    Patent number: 10215781
    Abstract: To provide a current sensor excellent in insulation resistance. A current sensor (1) includes a conductor (10); a support part (30) for supporting a signal processing IC (20); a magnetoelectric conversion element (13) configured to be electrically connectable to the signal processing IC (20), and arranged in a gap (10a) of the conductor (10) so as to detect a magnetic field generated by a current flowing through the conductor (10); and an insulation member (14) supporting the magnetoelectric conversion element (13).
    Type: Grant
    Filed: November 21, 2013
    Date of Patent: February 26, 2019
    Assignee: Asahi Kasei Microdevices Corporation
    Inventors: Kenji Suzuki, Hideto Imajo, Daigo Takagi
  • Current sensor substrate and current sensor
    Patent number: 9448256
    Abstract: It is intended to reduce manufacturing cost in a current sensor including a primary conductor having a U-shaped current path. A current sensor includes a primary conductor having a U-shaped current path, a support portion for supporting a magneto-electric conversion element, and a lead terminal connected to the support portion, and wherein the current path is not overlapped with the support portion in a plan view, while being formed so as to have a height different from that of the support portion in a side view.
