摘要： A cylindrical silver-activated phosphate glass base material 2 is placed inside a heater 1. The upper end of this base material 2 is set in a supporting section 3, and an extending section 4 provided in vertically movable fashion by means of a drive device is attached to the lower end thereof. As the base material 2 is softened by the heating of the heater 1, and the extending section 4 is lowered by operating the drive device, the base material 2 is extended and assumes a thin bar shape. The extension rate of the extending section 4 driven by the drive device is controlled by an external diameter control section 5, while detecting the external diameter, in such a manner that the external diameter of the extended portion is uniform. The extended portion 6 of the base material 2 is cut to uniform lengths, and the cut faces thereof are polished by a polishing device, thereby yielding a cylindrical dosimeter glass element 7a.
