PROBLEM TO BE SOLVED: To provide a flexible magnetic composition having improved magnetic characteristics and excellent workability and reliability without halogen in a magnetic composition containing magnetic powder in a binder. SOLUTION: The flexible magnetic composition is characterized by containing 50-70 capacity % of a magnetic powder body in the binder composed of an ethylene-methylacrylate copolymer, an ethylacrylate based polymer and an ethylene-ethylacrylate copolymer whose melt flow rate is 5-50 g/10 minutes and containing 20-80 wt% of the ethylene-ethylacrylate copolymer. Also, the weight ratio of the ethylene-methylacrylate copolymer and the ethylacrylate based polymer is 50/50-90/10. COPYRIGHT: (C)2005,JPO&NCIPI
