Summary:A fluorescent luminous tube is provided that has a getter mirror film formed in an arbitrary shape by illuminating a laser beam onto a getter. In order to form the getter film 32 , the rectangular ring-less getter 31 mounted on the anode substrate 11 is irradiated with the laser beam L from the outside of the front substrate 12 and thus is evaporated. In this process, when the illumination spot of the laser beam L is moved along the scanning line 33 , the rectangular getter mirror film 32 is formed around the scanning line 33 . The burnt region 34 , which has the same shape and size as those of the scanning line 33 , is formed using the laser beam L.
