PROBLEM TO BE SOLVED: To provide a fluorescent lamp capable of improving light flux better than before while keeping a high color rendering property. SOLUTION: The fluorescent lamp is provided with a light-emitting layer 8 composed of a mixed phosphor containing a blue green color phosphor activated by europium with an emission peak wavelength of 470 to 500 nm, a green color phosphor activated by terbium with an emission peak wavelength of 535 to 570 nm, and a red color phosphor activated by tin with an emission peak wavelength of 620 to 640 nm.
