Abstract
A silica-group composite oxide fiber formed of a composite oxide phase of an oxide phase (first phase) mainly made of a silica component and a metal oxide phase (second phase) excluding silica, in which the existent ratio of at least one metal element of a metal oxide constituting the second phase upward slopingly increases toward the surface layer of the fiber and a process for the production thereof.
