PROBLEM TO BE SOLVED: To provide a method for producing a dicyclopentadiene-modified phenolic resin usable as a raw material of a semiconductor sealing agent or the like. SOLUTION: The method for producing the dicyclopentadiene-modified phenolic resin comprises the steps of: reacting phenols with dicyclopentadienes in the presence of an acid catalyst to produce the dicyclopentadiene-modified phenolic resin; adding an alkaline compound and zeolite to the obtained reaction solution to deactivate the acid catalyst; and recovering the produced dicyclopentadiene-modified phenolic resin from the resulting reaction solution by filtration.
