To form a binding band of a comparatively inexpensive material, and also, to surely bind an article to be bound under various kinds of environments, and at the same time, to hold a sure bound state, and therefore, to reduce the cost, and to increase workability of the binding and reliability of the binding.

This binding band 1 comprises a strap part 2 and a head part 3. The strap part 2 has fastening parts 4 and 5 which are serially arranged in the longitudinal direction. The head part 3 has an insertion passage 12 through which the strap part 2 is passed, and fastening claws 17 and 18 which fasten the fastening parts 4 and 5. The binding band 1 is formed of a material of which the major components are a high density polyethylene and polypropylene. The formulation ratio for the high density polyethylene and polypropylene which are the major components can be selected in a range of 60 to 80 wt.% for the high density polyethylene and 20 to 40 wt.% for the polypropylene.
