Abstract
The present invention provides microsphere manufacturing method and apparatus capable of stable obtaining microspheres of a desired size and reducing facility cost. According to the method and the apparatus, to manufacture microspheres made of a second liquid in a first liquid, the first liquid is supplied into a first channel to flow therein and the second liquid is supplied to an intermediate part of the first channel through a second channel. The supply velocities of the first and second liquids are set such that the second liquid closes the first channel and the closing part of the second liquid is cut off due to a pressure difference between an upstream side and a downstream side to form microspheres.
