Zusammenfassung:	PROBLEM TO BE SOLVED: To provide foaming microspheres with spherical particles, with a very sharp particle distribution and showing a low viscosity slurry giving sharp foaming and a uniform foam product. SOLUTION: The spherical foaming microspheres enclosing a foaming agent in an outer shell of a polymer are characterized in that (1) an average particle size of the foaming microspheres is in a range of 3-100 μm, (2) a coefficient of variation of particle distribution of the foaming microspheres is at 1.50% or less and (3) the foaming microspheres are not aggregated.
