PROBLEM TO BE SOLVED: To solve problems of limits of sizing agent and change of color of dye in printing paste by stopping the use of a reducing substance and an alkaline substance conventionally adopted as a discharge printing agent and simultaneously to obtain a discharge printing agent for a synthetic fiber material, which has a clear hue, no unevenness of color and printed patterns having remarkably sharp pattern edges and produces a synthetic fiber material of discharge printing processing extremely safely with a reduced load to the environment and apparatuses. SOLUTION: The discharge printing agent for a synthetic fiber material comprises a fatty acid ester nonionic surfactant containing at least one group represented by general formula (1) -O(AO)<SB>n</SB>COR (wherein A is a 2-4C alkylene group; R is a hydrocarbon group; n is a repeating unit) in the molecule and powder of at least one inorganic material selected from the group consisting of a mineral material, a carbon material and a ceramic material as discharge printing components.
