To provide a magnetic substance striped array sheet which has a needlelike magnetic substance excellently arrayed in a predetermined striped pattern, and also has high magnetic permeability and is thin and rich in flexibility.
A water-repellent layer 12 is formed on a resin film 11, and a striped pattern region 14 is formed which is disposed in a surface region of the water-repellent layer and has hydrophilicity relatively to the water repellence that the water-repellent layer has. The needle like magnetic substance 15 is aligned and gathered in the striped pattern region to form a magnetic substance striped pattern 13. A plurality of mutually separated magnetic substance stripes form the magnetic substance striped pattern, and a plurality of magnetic substance striped array sheets are laminated having magnetic substance stripes of respective layers orthogonally to each other to constitute an RFID magnetic sheet. Thus, the lattice-shaped magnetic substance striped pattern is formed to constitute an electromagnetic shield sheet.
