PROBLEM TO BE SOLVED: To provide a method of manufacturing vulcanized rubber moldings with such advantages that almost no release agent is allowed to remain as a residue product, and high-quality vulcanized rubber moldings free from cracking by virtue of effective inhibition, and further, the loading properties of a raw material rubber and the releasability of a finished product (drawability) are satisfactory. SOLUTION: This method of manufacturing vulcanized rubber moldings involves the process to form the vulcanized rubber moldings using a raw material rubber and release the vulcanized rubber moldings using a release agent. This release agent is composed mainly of at least, one kind selected from the group consisting of glycerine, a glycerine derivative, polyglycerine, a polyglycerine derivative, a glycerine fatty ester with an HLB value of not less than 14 and a polyglycerine fatty ester with an HLB value of not less than 14.
