PROBLEM TO BE SOLVED: To provide a bulb type fluorescent lamp restraining the occurrence of a crack in a bulb or a globe, even upon the exposure thereof to a vibration or a shock. SOLUTION: A bulb adhesive 5 for fastening both ends 1a of a fluorescent light emitting tube 1 to the holding part 2a of a holder 2, is formed to have higher hardness than a globe silicone adhesive 4 for fastening a globe 7 to a case 3 or the holder 2. Also, a bulb type fluorescent lamp has the globe 7 fixed to allow a slight vibration, while the fluorescent light emitting tube 1 is firmly fixed. As a result, stress hardly acts on the globe 7, even if a bulb type fluorescent lamp is subjected to a vibration or a shock, and a bulb 1c hardly comes in contact with the holder 2 or the globe 7, thereby reducing the occurrence of a crack. |
