Abstract
A fabricating method for a quartz vial having a body for containing a substance, a bottom closing a lower end of the body, a cylindrical neck disposed above the body, and a cylindrical mouth disposed above the neck and having an outer diameter larger than that of the neck includes the steps of forming an outer peripheral surface of the neck by shaving, and joining by thermal fusion, to the neck, the body that is separately fabricated. Thus, quartz vials having a predetermined shape can be mass-fabricated.
