Abstract
The present invention relates to a detecting apparatus for detecting a magnetic minute substance. The detecting apparatus of the present invention can detect continually at a high sensitivity an entity of fine particle, without destroying an object to be inspected. The detecting apparatus comprises a magnetic field generator and a magnetic sensor. The magnetic field generator generates a magnetic field having a right angle to the traveling direction of the object to be inspected. The magnetic sensor includes a SQUID for inspecting a drift of the magnetic field that is parallel to the magnetic field.
