摘要： In a fluorescent lamp having a plurality of glass tubes that are connected with each other to form a discharge path, spacers that do not drop off even with insufficient accuracy of a gap between the glass tube are provided in a gap between the connected glass tubes, so as to improve the gap compression resistance and the torsion resistance. Each spacer is composed of a plurality of tonguelets and a bridge. The tonguelets are in contact with surfaces of the glass tubes and are connected by the bridge that is directed in an axial direction of the glass tubes.
