PROBLEM TO BE SOLVED: To provide a method for producing a boa, by which the boa capable of exhibiting many effects for health without fading the color can be produced. SOLUTION: This method for producing the boa is characterized by infiltrating, impregnating or inserting a negative ion-producing processing agent comprising fine natural mineral particles emitting an energy for producing the negative ion, substantially not emitting radiations and not containing an injurious substance into fibers constituting the boa, when the boa is produced, dyed and processed.
