Abstract:
1. A process for producing a microsphere, comprising: separating a disperse phase from a continuous phase by a substrate having a through-hole; and extruding the disperse phase into the continuous phase through the through-hole, wherein at least one metal substrate is used, the metal substrate comprising a through-hole, with a width of 0.5 to 500 μm, a depth of 10 μm to 6000 μm, a ratio of the width to the depth of the through-hole (width/depth) of 1 to 1/30 (1/1 to 1/30), and a recess is around an opening of the through-hole on the side where a microsphere is formed.
