PROBLEM TO BE SOLVED: To provide a diamond electro-deposited blade which can suppress run-out and flexure of the diamond electro-deposited blade, and can improve roughness of a cut-off surface and cut-off speed. SOLUTION: In an endless belt shape diamond electro-deposited blade 1 for cutting-off semiconductor crystals such as gallium arsenide, silicon, diamond grains 3, 4 having different height of a cutting edge are alternately arranged at regular intervals on an endless belt shape base metal 2, and a cutting-off width for the diamond grains 3 having a low cutting edge is larger than that for the diamond grains 4 having a high cutting edge.
