PURPOSE: A catalyst for epoxidation of dicyclopentadiene dimer and a manufacturing method thereof are provided to be able to show a high selectivity to dicyclopentadien dimer with a large molecular size and a high conversion ratio, and to be able to obtain a dicyclopentadiene dimer epoxy compound with a high yield. CONSTITUTION: A catalyst for epoxidation of dicyclopentadiene dimer has a structure in which metals in a zeolite molecular sieve of macro pores more than 7 angstrom are substituted with titanium. The catalyst is a heterogeneous catalyst used in a process of manufacturing dicyclopentadiene dimer epoxy compound by epoxidation of dicyclopentadiene dimer. A manufacturing method of the catalyst comprises the following steps: a step of processing a zeolite molecular sieve of macro pores more than 7 angstrom with acid; and a step of substituting aluminum of the acid-treated zeolite molecular sieve with titanium by stirring the acid-treated zeolite molecular sieve with titanium precursor.
