Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate unevenness on the surface and make the fiber layout pattern undetectable from outside so as to prevent forgery and alteration, by causing a magnetic card to have a multilayer structure including a white polyester layer containing a magnetically sensitive fiber of a thermoplastic resin. SOLUTION: In this magnetic card, a sheet member C containing a magnetically sensitive fiber is stacked between two polyester resin film layers A, B, using a polymer adhesive D and a crosslinking agent. In this case, the relation of 0.1T1
