PURPOSE: A manufacturing method of a buffer pad having a hollow part is provided to manufacture various functional buffer pads by coupling unit pads having various colors and material properties to each other. CONSTITUTION: A manufacturing method of a buffer pad(P) having a hollow part is as follows. Multiple unit pads(200) are manufactured by cutting a material(100) having multiple insertion holes(210) in a plate shape(S1). The unit pads are piled up, and multiple through holes(220) communicating with each other are formed by coaxially arranging the insertion holes(S2). A preliminary block(400) is formed by inserting rod members(300) into the through holes and protruding both ends of the rod members from the unit pads(S3). The preliminary block is put into a mold(500) and sealed(S4). A molded block(600) is formed by heating the mold having the preliminary block(S5). The molded block is separated from the mold, and the rod members are removed from the molded block(S6).
