A quartz specimen is immersed in hydrofluoric acid to expose a layer to be analyzed located at a prescribed depth. On an exposed surface, a decomposition liquid such as hydrofluoric acid or nitric acid is dripped to decompose only an extremely thin layer to be analyzed, followed by recovering of the decomposition liquid. The decomposition liquid is quantitatively analyzed by use of atomic absorption spectroscopy (AAS) or the like to measure an amount of metal contained in the decomposition liquid.

With thus obtained diffusion coefficient as an index, quartz material in which metal diffuses with difficulty is sorted out. With thus sorted quartz material, a quartz member used for semiconductor manufacturing equipment such as a quartz tube is manufactured.
