To provide a multifunctional sheet film for radiating a minus ion and simultaneously radiating a far infrared ray.

A multifunctional sheet film member comprises an adhesive sheet or the like obtained by coating, mixing, molding a resin composition for radiating the minus ion and simultaneously radiating the far infrared ray or laminating a laminated sheet or an adhesive layer. Thus, conveniently and lightly cut sheet films in various sizes are simply adhered, can conveniently supply the minus ion having effects of stabilizing an autonomic nerve, activating a cell and improving a health, and effects of collecting and performing multiple functions of radiating the far infrared ray for accelerating a blood circulation are achieved.
