[Claims for Utility Model Registration] 1. The peripheries of first and second glass substrates whose inner surfaces are coated with a phosphor film are sealed by a spacer, and mercury is depressurized in a cell formed by sealing the peripheries. A gas containing steam is enclosed, and
In a fluorescent lamp in which a pair of cold cathodes are arranged facing each other in parallel, a cell gap formed by the inner surfaces of each of the first and second glass substrates is placed at the center of the cell in a direction parallel to the cold cathode. A flat fluorescent lamp characterized by being smaller at the center and larger at the periphery. 2 When the size of the cell gap at the center of the cell is a, and the size of the periphery of the cell is b,
The flat fluorescent lamp according to claim 1, which is a utility model, and has an a/b value of 0.70 to 0.98.
