Magnetic measurement device manufacturing method and magnetic measurement device

Abstract

Summary: [Problem] To provide a magnetic measurement device manufacturing method and a magnetic measurement device capable of improving sensing performance. [Solution] According to an embodiment of the present invention, a magnetic measurement device manufacturing method is provided. The method includes: in a preparation step, preparing a sensing wire having magnetic anisotropy, a sensing pickup coil wound around the sensing wire, a pulse generation circuit configured to supply a pulse current to the sensing wire, and a sensing circuit configured to measure, when a set sensing delay time has elapsed since supply of the pulse current started, an induced electromotive force for sensing generated in the sensing pickup coil by the pulse current. In a setting step, after supply of the pulse current starts, the sensing delay time is set to exclude a singular period in which the S/N ratio of the induced electromotive force for sensing is low.
