PROBLEM TO BE SOLVED: To provide a circular fluorescent tube packaging case which is in a sleeve-type case instead of a conventionally used box-shaped case and can be produced with reduced steps of processes for fabrication with the amount of corrugated board reduced. SOLUTION: The case includes a surface board 11, a back board 12 and paired side boards 13, 14 which connect the surface board and back board together, and a square tube body 16 in a rectangular cross section having internal dimensions virtually corresponding to the width and height of the circular fluorescent tube 15 to be housed is a main body of the case. Tuck-in pieces 20, 21 which come into contact with the inside of the circular fluorescent tube 15 for preventing its movement are provided on symmetrical positions at the surface board 11, and the tuck-in pieces 20, 21 are joined to the surface board 11 respectively with the first creases 22, and each of the tuck-in pieces has a first bendable piece 23 in the height virtually the same as the circular fluorescent tube 15 and a second bendable piece 25 which is connected with a second crease 24 to the first bendable piece 23 and put between the circular fluorescent tube 15 and the back board 12 at the time of use.
