A method for producing a ceramide microparticle dispersion causes a first mixture in a liquid state containing a ceramide and sterols and a second mixture in a liquid state containing water to separately flow, merges the first and second mixtures together, and passes a fluid formed by merging the first and second mixtures together through a small hole having a hole diameter of 0.03 mm or larger and 20 mm or smaller. A mass ratio of a content of a water-soluble organic solvent to a content of the ceramide in the first mixture is 0 or more and 30 or less.
