PURPOSE: A modified sulfur binder is provided to obtain physical properties which can re-melt the modified sulfur binder at 100 °C or less by using alkylamines together with a dicyclopentadiene-based modifier. CONSTITUTION: A modified sulfur binder comprises sulfur and a modifier of the sulfur. The modified sulfur binder comprises 0.01-100.0 parts by weight of dicyclopentadiene-based modifier, 0.01-200 parts by weight of alkylamine which are melt-mixed. The dicyclopentadiene-based modifier is (a) single dicyclopentadiene, (b) a mixture in which at least one of dicyclopentadiene, cyclopentadiene, dicyclopentadiene derivative, cyclopentadiene derivative, or a mixture at least one of dipentene, vinyl toluene, styrene monomer, dicyclo pentene is added to component (a) or (b).
