摘要：
A magneto-impedance element used for detection of a magnetic substance has a structure that can trap magnetic substances locally in a predetermined band-like region on the lateral surface thereof or a structure that can detect the presence of a magnetic substance based on a change of the impedance in response to application of magnetic fields. The magneto-impedance element is used to provide a detection apparatus and a detection method that can easily detect a magnetic substance with high precision.
