Summary:The optical fiber fixing member made of glass, especially optical fiber guide block, is conventionally produced by a mechanical processing. However, the mechanical processing has problems that a production cost becomes high and mass-production is difficult. The problems above can be solved by the present invention providing a method for producing an optical fiber fixing member comprising: disposing a glass shaping preform whose plane view resembles to the plane view of the molded article and whose faces to be positioned in the pressurizing direction during press-molding assumes planes or outwardly convex curved surfaces, in a mold having a cavity of a given shape; and heating the glass shaping preform up to a temperature at which the glass shaping preform can be mold-shaping and thereby press-molding it into a molded article having at least one edge formed of a free surface.
