Abstract
A compact and superior magnetic marker for an electronics apparatus for surveillance of article comprises at one or more wire members and a plane member contacting substantially directly to each other. An angle of the magnetic easy axis of the plane member relative to the longitudinal direction of the wire member is between 40.degree. and 90.degree. to show large Barkhausen reversal. An influence of demagnetizing field can be reduced by using the simple structure. The magnetic marker can be produced continuously at a low cost.
