摘要： Provided is a method that can manufacture a glass material having excellent homogeneity by containerless levitation. A block (12) of glass raw material is heated and melted by irradiation with a plurality of laser beams with the block (12) of glass raw material held levitated, thus obtaining a molten glass, and the molten glass is then cooled to obtain a glass material. The plurality of laser beams include a first laser beam (13A) and a second laser beam (13B). A size (θ) of an angle formed between the first laser beam (13A) and the second laser beam (13B) is 0° or more but less than 180°. A center (C1) of a spot (S1) of the first laser beam (13A) on the surface of the block (12) of glass raw material and a center (C2) of a spot (S2) of the second laser beam (13B) on the surface of the block 12 of glass raw material are different from each other.
