The invention discloses a band saw blade manufacturing method and a band saw blade. The band saw blade manufacturing method comprises the steps of S1, subjecting a steel band to tooth forming; S2, subjecting the steel band subjected to tooth forming to thermal treatment; S3, grinding front face and back face of the band saw blade subjected to thermal treatment so that the front face and back face satisfy Ra <0.8 Mum; S4, subjecting the band saw blade that is ground to tooth passivating to remove tooth tip burrs and to form round corners or terraces at tooth tips; S5, subjecting the passivated band saw blade to tooth dividing to obtain the non-ground band saw blade. Direct entry in conventional sawing phase without grinding is achieved, and the low-efficiency grinding step is omitted.
