<；P>；PROBLEM TO BE SOLVED: To provide a tubular body by which a desired hue with brightness is acquired and the brightness is smoothly changed. <；P>；SOLUTION: The tubular body 10 comprises a decorative layer 18 which includes: an outer metallic thin film layer 18b for directly reflecting incident light E； and an inner chromatic layer 18a for reflecting the light transmitted through the metallic thin film layer 18b, and where the rate of the strength of each reflection light is changed without steps from a brightness area, where metallic layer reflection light reflected against the metallic thin film layer 18b is stronger than chromatic layer reflection light reflected against the chromatic layer 18a, to a chromatic area where the metallic layer reflection light is weaker than the chromatic layer reflection light. <；P>；COPYRIGHT: (C)2007,JPO&INPIT
