PROBLEM TO BE SOLVED: To lengthen the cutting-bending service lift of a plectrum type saw blade 19 by improving straightness of the plectrum type saw blade 19. SOLUTION: This plectrum type saw blade is constituted so that a shaking-out corner part 23C of a plectrum tooth 23 is shaken out larger by 0.1 mm or more than a chamfer corner part 25C of a bevel tooth 25, and is constituted so that a side surface clearance angle of the bevel tooth 25 becomes smaller by 1°or more than a side surface clearance angle of the plectrum tooth 23, and is constituted so that the tooth height of the bevel tooth 25 becomes higher than the tooth height of the plectrum tooth 23 in a height difference up to 0.3 mm from 0.15 mm.
