Zusammenfassung:	Provided is a silicone embossing rubber roller having no fine depression defects on the surface, and furthermore, not liable to produce protrusions on an embossed plastic film surface. This silicone rubber roller for embossing is such that the silicone rubber layer on the surface contains spherical solid particles, and the spherical solid particles having a particle size of 0.8 [mu]m or smaller and the spherical solid particles having a particle size of 30 [mu]m or larger respectively occupy 1% or less of the volume of all the spherical solid particles.
