PROBLEM TO BE SOLVED: To provide a self-emulsifying composition which is excellent in at least one of self-emulsifying property, composition dispersibility, emulsion stability and absorbability, and in which ethanol is not added or the addition concentration is low. SOLUTION: The total amount of at least one compound selected from the group consisting of ω3 polyunsaturated fatty acids, pharmaceutically acceptable salts and esters thereof is in the range of 50 to 95% by mass, and the hydrophilic-lipophilic balance is 10. A self-emulsifying composition containing the above emulsifier in a range of 5 to 50% by mass, wherein the ethanol content is 4% by mass or less based on the total mass of the compound and the emulsifier.
