Abstract
A fine magnesium oxide particle dispersion liquid containing an aprotic solvent, and fine magnesium oxide particles that are dispersed in the aprotic solvent, wherein the dispersion liquid has D50 of 200 nm or less in a particle size distribution as measured by a dynamic light scattering method, and has a content rate of coarse particles having an average particle diameter of 500 nm or more of less than 1%, and a method for producing the fine magnesium oxide particle dispersion liquid.
