摘要： A lighting device having a circuit board with a fine tube inserting opening, and electric parts, outputs high-frequency power to an emission bulb having a bent tube. A cover member has a cap on the one end side, and a holder on the other end side. A fine tube protruding from the end of the emission bulb, and having a bent portion on the middle portion thereof, is disposed so that the tip end portion from the bent portion is positioned close to the axis passing through the center of the cap as compared with the base portion from the bent portion on the side of the emission bulb. A principal amalgam is contained at a position on the cap side as to the position where the electric parts, which emit relatively a great quantity of heat, have been disposed. The bent portion is disposed on the side of the emission bulb as to the circuit board, and the tip end portion is inserted into the fine tube inserting opening, and is extended on the cap side. According to this simple structure, the light quantity rising property can be improved, and there can be provided a bulb-shaped fluorescent lamp excellent in assembling property.
