A non-crystalline alloy far infrared heating element and heating band device are disclosed, which are applied in the field of far infrared heating. The non-crystalline alloy far infrared heating element comprises a heating element, an insulating layer, and a protective outer shell. The insulating layer is wrapped around the heating element. The protective outer shell is wrapped around the insulating layer. The heating band device comprises: a non-crystalline alloy far infrared heating element, a shield layer and a power connection lead. The shield layer wraps the insulating layer of the non-crystalline alloy far infrared heating element. The power connection lead is used to connect the two ends of the heating element of the non-crystalline alloy far infrared heating element. The invention heats the heating element to improve the thermal to electrical conversion efficiency and heat conversion performance. Moreover, the protective outer shell is wrapped around the insulating layer, which makes the outdoor application products have a safer and more reliable double-layer insulation structure, and can also play a good role in corrosion resistance and wear resistance, making it have a wider range of applicability and longer service life.
