PROBLEM TO BE SOLVED: To provide a disjointing bobbin capable of surely moving the winding start end part of a wire rod inside a coiled wired rod. SOLUTION: In this disjointing bobbin formed by a lower flange, a plural- split inner drum with an upper flange, a sleeve for locking the plural-split inner drum with the upper flange, and a bolt for fixing the sleeve and the lower flange, the lower flange is formed by one lower flange base, eight disjoint type lower flanges and eight lower flange stopping bolts.
