A dyeing bobbin is provided to use metal as materials, thereby smoothly communicating dyes and preventing the pollution of the dyes. A core(1) is made of metal and has a coil spring shape. A wall body(2) is arranged with a constant distance at the outer circumference of the core. Plural support rods(20) having a prominence and depression groove(21) are welded at the outer surface of the core longitudinally. Reinforcing rims(3) are coated at the upper and lower ends of the core and wall body and have combining grooves(31) and combining jaws(32) formed oppositely of the core and wall body. The reinforcing rim is made of epoxy resin.
