Abstract: A light emitting string is produced by forming a fluorescent layer on a fluorescent layer support member having an opening and configured such as to protect the fluorescent layer, and inserting the fluorescent layer support member into a minute tube. Therefore, when the fluorescent layer support member is inserted into the minute tube, the fluorescent layer is prevented from contacting the interior wall of the minute tube. This prevents the chipping, the separation and the cracking of the fluorescent layer, thereby improving the yield in production of plasma light emitting strings.
