Abstract:
Provided are a method for producing a phosphor-encapsulating capillary tube in which, when a phosphor is encapsulated thereinto, fluorescence from the phosphor is less likely to leak from an end of the capillary tube; and such a phosphor-encapsulating capillary tube. One end portion 10A of an elongate glass capillary tube 10 having an outer shape of a transverse cross-section elongated in a width direction thereof is heated until the one end portion 10A of the glass capillary tube 10 has been melted, integrated, and thus sealed.
