Provided in a facile manner are a black synthetic quartz glass with a transparent layer, which meets demands for various shapes, has a black portion satisfying required light shield property and emissivity in an infrared region, keeps a purity equivalent to that of a synthetic quartz glass in terms of metal impurities, has a high-temperature viscosity characteristic comparable to that of a natural quartz glass, can be subjected to high-temperature processing such as welding, does not release carbon from its surface, and is free of bubbles and foreign matter in the transparent layer and the black quartz glass, and at an interface between the transparent layer and the black quartz glass, and a production method therefor.
