Title
(EN) GLASS TUBE PRODUCTION METHOD
Abstract
(EN)

A method for manufacturing a glass tube is disclosed that includes the step of forming a through hole in a tube wall of a glass tube with two ends including a first end and a second end, each having an opening, near the first end. The method further includes the step of forming a sealed portion by performing thermal processing on a predetermined portion of the glass tube between the first end and the through hole after the formation of the through hole.
