To provide capsular fine particles comprising an olefinic polymer which have a uniform size and a uniform particle diameter, and which are spherical and free from the coagulation between particles. Capsular fine particles comprising an olefinic polymer of which a ratio (L/M) of the outer diameter (L) to the inner diameter is 1.1 to 6.0 and an average diameter is 0.6 to 40 mum. |
