Abstract
PURPOSE:To stabilize the operation of a magnetic reluctance effect element at the time of absence of magnetic field by forming the magnetic reluctance effect element of a magnetic film via an insulating layer on the surface of a lead frame formed of a magnetic material. CONSTITUTION:A magnetic reluctance effect element pattern 2 in which a lead frame 6 is formed of ferromagnetic material such as Ni-Fe or Ni-Co, a substrate 1 of silicon or the like is secured onto the lead frame 6 and a magnetic film of Ni-Fe or Ni-Co or the like is formed on the surface of the substrate 1 is formed. The pattern 2 is connected to lead frames 6, 6' via bonding wires 7. Bias magnetic field can be applied to the pattern 2 by magnetizing the magnetic lead frame 6, thereby stabilizing the operation at the time of absence of magnetic field.
