In a method of producing a spacer for a display apparatus by heat drawing
a base glass material having a cross section with different dimensions in
a longitudinal and lateral directions and then cutting into a desired
length, a base glass material in which a high-viscosity glass material is
combined on both ends of a low-viscosity glass material is drawn within a
temperature range in which both glass materials have different
viscosities. Such method avoids a deformation of the spacer such as an
expansion or a rounding at the longitudinal ends in the cross section of
the spacer or a constriction in an intermediate portion in the
longitudinal direction.
