PROBLEM TO BE SOLVED: To provide a method by which manufacturing of a fluorescent lamp is carried out by supplying granular materials containing mercury to a glass tube without bringing about abrasion as much as possible. SOLUTION: In tilting of a container 22 leftward (a), an escape plate 40 slides to the right, a separation hole 42 opened on the escape plate 40 takes a position below a group of granular materials (b). Then, one piece of granular material fits into the separation hole 42. Successively, on tilting the container 22 to the right (c), the escape plate 40 slides to the left and the separation hole 42 is fitted into a supply hole (aperture) 24. The granular materials in the separation hole 42 fall into the supply hole, and supplied to inside the glass tube via a prescribed supply route therefrom. The container and the escape plate are shaken side to side, by which the granular materials are moved and rolled inside the container. As a result, the granular materials are prevented from staying in the same position in the container, therefore, a state where the granular materials are abraded caused by the stay is avoided.
