A method for producing a ceramide microparticle dispersion causes each of a liquid first mixture containing ceramide and sterols and a liquid second mixture containing water to flow and merges the two, and the merged fluid of said first and second mixtures is passed through a pore with a pore diameter of 0.03 mm to 20 mm. The mass ratio of the content of water-soluble organic solvent with respect to the ceramide content in the first mixture is 0 to 30.本發明之神經醯胺微粒子分散物之製造方法係使含有神經醯胺及固醇類之液體之第1混合物與含有水之液體之第2混合物分別流動並使該等合流，再使該等第1及第2混合物合流後之流體通過孔徑為0.03 mm以上且20 mm以下之細孔。第1混合物中之水溶性有機溶劑之含量相對於神經醯胺之含量的質量比為0以上且30以下。
