PROBLEM TO BE SOLVED: To provide a manufacturing method of a dispersion liquid of fine particles of crystalline solid fat in which the average particle size of fine particles is less than 1,000 nm. SOLUTION: The manufacturing method of the dispersion liquid of fine particles of crystalline solid fat includes: a process of causing a first liquid of a melted oily mixture which includes the crystalline solid fat having at least one selected from monoethers and diethers of straight chain saturated alcohols, respectively having the number of carbon in the range of 16-22, and monoesters and diesters respectively between aliphatic alcohols and straight chain saturated aliphatic acids having the number of carbon in the range of 16-22 and a hydrophilic nonionic surface active agent, and a second liquid of an aqueous component to respectively flow and come into contact with each other such that the first liquid and the second liquid come into a coexisting state; a process of causing the first liquid and the second liquid turned into a coexisting state to flow through a micro pore for mixing to prepare an emulsion liquid in which the first liquid is dispersed and emulsified into the second liquid; and a process of cooling the emulsion liquid to solidify the crystalline solid fat into fine particles having the average particle size less than 1,000 nm.
