PROBLEM TO BE SOLVED: To provide porous fine particles, different from vesicles formed from a surfactant or a polymer, having pores on their surfaces and also having characteristics which have not seen in an inorganic porous material represented by zeolite-mesoporous silica. SOLUTION: The porous fine particles formed by spherically agglomerating tubular structural materials are produced by a method comprising a step of dissolving each of a peptide lipid expressed by the following formula (I): RCO(NH-CHR'-CO)<SB>m</SB>OH [wherein, R is a 6-24C hydrocarbon group; R' is an amino acid side chain; and (m) is an integer of 1 to 10] and a metal salt in a solvent heated to a temperature at or lower than its boiling point, a step of mixing each of the solutions, a step of standing the above mixture still at a room temperature, a step of forming the tubular structural materials by self-agglomerating in the solution and a step of spherically agglomerating each of the tubular structural materials to precipitate as the porous fine particles.
