A recording medium comprising a paper base containing pulp fibers as a main component, and the paper base contains a plurality of magnetic wires, wherein:
- each of the magnetic wires comprises a magnetic metal wire material having a surface coated with a layer of an insulating material,
- a magnetic coercive force of each of the magnetic metal wires is 10.3A/m or more and about 30 A/m or less and each of the magnetic metal wires has a Barkhausen effect,
- each of the magnetic wires begins at an edge of one short side of the recording medium, extends along a longitudinal direction of the recording medium, and ends at an edge of an opposite short side of the recording medium, and each of the magnetic wires is arranged as a curved line that comprises at least one convex portion and at least one concave portion along the longitudinal direction of the recording medium.
