To provide an inexpensive band saw blade which has a longer length that can be coated in one coating processing, can perform cutting with high productivity, and has less burrs.SOLUTION: A band saw blade (1) comprises: a belt-like endless body part (11); a tooth part (12) in which a tooth row (TG) that is a set of a prescribed number of teeth including a set tooth (Rw) is repeatedly formed on one edge side of the body part (11); and a coat layer (13) which is formed on a surface of teeth (12a) of the tooth part (12). The set tooth (Rw) has a first impression part (T82) as a recess (12b) on the coat layer (13) on an outer face in a swing direction, and a thickness of the coat layer (13) in the recess (12b) of the first impression part (T82) is thinner than a thickness of portions other than the recess (12b) of the coat layer (13).SELECTED DRAWING: Figure 11 【課題】１回のコーティング処理でコーティングできる帯鋸刃の長さがより長く、生産性が高い切断加工でバリが生じにくく安価な帯鋸刃を提供する。【解決手段】帯鋸刃（１）は、帯状で無端状の胴部（１１）と、胴部（１１）の一縁側に、アサリ歯（Ｒｗ）を含む所定数の歯の組である歯列（ＴＧ）が繰り返し形成された歯部（１２）と、歯部（１２）の歯（１２ａ）の表面に形成されたコート層（１３）と、を備える。アサリ歯（Ｒｗ）は、振り出し方向の外面の前記コート層（１３）に凹部（１２ｂ）としての第１圧痕部（Ｔ８２）を有し、第１圧痕部（Ｔ８２）の凹部（１２ｂ）におけるコート層（１３）の厚さは、コート層（１３）の凹部（１２ｂ）以外の部分の厚さよりも薄い。【選択図】図１１
