ABSTRACT:
A method of manufacturing glass parts for connection of glass fibers is provided, which can improve the accuracy of the cross-sectional size of a through hole in the glass part. A mother glass having a similar cross section to a desired cross section of a glass part having a through hole is prepared, and the prepared mother glass is drawn while it is heated. The mother glass is made of a glass having a maximum devitrification speed of 100 μm or less per minute.
