Abstract
A detection device and a detecting method using the detection device are provided in which a magnetic particle is used as a marker particle, and the ratio of a region with reversed magnetization to the whole area of a free layer of a magnetoresistive effect film is increased by a stray magnetic field generated through a biochemical reaction from the magnetic particle remaining on a surface of the magnetoresistive effect film, so that a large detection signal is obtained and obtained detection data can be stored with stability.
