To provide a manufacturing method of a substrate material for an optical device, capable of forming the substrate material having a surface shape of relieving warping of the substrate material in a process of laminating a luminescent layer only by a grinding process by a grinder.
The manufacturing method of the substrate material for the optical device comprises: a first grinding process of flattening a surface Wa of a plate-like work W executed after adjusting a contact surface 3da in a grinding wheel 3d possessed by grinding means 3 and the surface Wa of the plate-like work W opposed to the contact surface 3da in parallel by an adjustment shaft 5 indicated from a first inclination indicating part 6a; and a second grinding process of forming a second grinding surface of a center recessed shape by grinding a new upper surface Wb of the plate-like work W by sending the grinding means 3 for grinding after setting so that the contact surface 3da of the grinding wheel 3d comes into contact with a central part earlier than with an outer peripheral part of the upper surface Wb by adjusting an inclination of the upper surface Wb of the plate-like work W after holding the flattened surface Wa by a holding surface 2a, by the adjustment shaft 5 indicated from a second inclination indicating part 6b.
