PROBLEM TO BE SOLVED: To enable to radiate heat of a phosphor without relying on an extra heat-radiating member. SOLUTION: In the cold-cathode fluorescent lamp exciting the phosphor to emit light by irradiating electrons on a phosphor screen of the phosphor 14, a surface area of the phosphor screen is increased by providing ruggednesses 18 on nearly a whole surface of the phosphor screen, whereby, improvement in heat radiation is attained by increasing an emission volume of secondary electrons e2 without the need of extra heat-radiating members.
