Abstract
A magneto-impedance element with a longitudinal columnar section whose cross section about a longitudinal center axis is either a circle or a polygon inscribed in the circle, and which has a trap region configured to trap a magnetic substance that is formed in a band region extending along at least one of two lines of intersection between a plane containing the center axis and a lateral surface of the longitudinal columnar section and a non-trap region for a magnetic substance that is a region of the lateral surface of the magneto- impedance element excluding the trap region. 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.
