Abstract
A magnetism detection device includes: a transmission line set having a transmission line including a linear first conductor including a magnetic material; and a detector that: inputs, from a first end of the transmission line set, a pulse signal as a first incident wave and detects, at the first end, a first reflected wave of the first incident wave; inputs, from a second end opposite to the first end, a pulse signal as a second incident wave and detects, at the second end, a second reflected wave of the second incident wave; and detects a strength of a magnetic field applied to the transmission line set based on compositing of the first reflected wave and the second reflected wave.
