PROBLEM TO BE SOLVED: To obtain a releasing agent having excellent working circumference and coating uniformity and a little development of thermally decomposing gas by composing the agent of a mixture of a powdery solid lubricator, a stickiness improving agent composed of organic or inorganic compound and volatilizing solvent. SOLUTION: Desirably, the powdery solid lubricator has 0.1-10μm average grain diameter, and the grain having <0.1μm grain diameter accounts for <5 wt.% and the grain having >10μm grain diameter accounts for <5 wt.% in the powdery solid lubricator. Further, the stickiness improving agent is mixed in 0.05-15 pts.wt. based on the 100 pts.wt. of the powdery solid lubricator, and the b.p. of the volatilizing solvent is in the range of 40-150 deg.C and the firing pt. thereof is >=250 deg.C. Desirably, at the time of producing, this releasing agent is composed of 1-70 pts.wt. the powdery solid lubricator, 0.0005-10.5 pts.wt. the stickiness improving agent and 98.995-19.5 pts.wt. the volatilizing solvent. Since this releasing agent is sprayed onto the wall surface of a die in the droplet state, the spattering is not developed to the circumference with the flow of wind and the working circumference is improved, and the good coating is obtd. because this agent is uniformly dispersed.
