To provide a fluorescent lamp which is suitable, for example, for a cold cathode fluorescent lamp and in which a fluorescent tube and a stem are made of synthetic resin or rubber and a breakage can be avoided by making a weight lighter and raising impact resistance and while an operation safety is secured, a heat radiation from these units is controlled and a rationalized arrangement is realized and a housing and a space can be made smaller, and in which a shape and ornamental flexibility can be obtained and while a variety of fluorescent tubes can be produced, productivity can be increased by dispensing with coating of a phosphor material and production cost can be reduced.

The fluorescent lamp is provided with a fluorescent tube 2, on an inner face of which a phosphor layer 3 is formed, and a stem 5 which fixes an electrode 7 placed in the above tube 2 and seals both ends of the above fluorescent tube 2 and seals filling gas in the above tube 2. The above fluorescent tube 2 is made of synthetic resin having heat resistance and transparency.
