The present invention relates to a fine spherical particle having uniform molecular orientation having uniform molecular orientation, which is useful in fine chemical fields or electronic and information fields, such as a functional material and a medical material, using membrane formation of a bicephalic compound; a spherical microcapsule encapsulating a hydrophilic core substance; and a process for producing the same. The fine spherical particle can be produced by immersing a substrate having hydrophilicity in an aqueous solution of a salt of the compound represented by the following formula (1) to precipitate the fine particle under an acidic atmosphere. wherein R represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms; n is an integer of 8 to 20; and m is an integer of 1 to 3. The spherical microcapsule encapsulating a fine particle of a hydrophilic core substance is produced by immersing a substrate having hydrophilicity in an aqueous solution in which a metal salt of the compound represented by formula (1) and the hydrophilic core substance are dissolved; and allowing the aqueous solution to stand under an acidic atmosphere to precipitate the fine particle. The resulting fine spherical particle and the spherical microcapsule has a particle diameter of 0.01 to 100 .mu.m.
