Beschreibung
Zusammenfassung:	The present invention provides a method for producing a porous silicone sheet comprising a freezing step of freezing a wet gel of a porous silicone body having communicating pores and a three-dimensional network silicone skeleton which forms the pores and which is formed by a copolymerization of a bifunctional alkoxysilane and a trifunctional alkoxysilane, to obtain a frozen body, a sheet forming step of forming the frozen body into a sheet to obtain a porous silicone sheet, and a cleaning step of cleaning the porous silicone sheet. According to the method of the present invention, a porous silicone body from which impurities have been sufficiently removed can be produced. In the course of the production, occurrence of fracture of a wet gel can be effectively prevented.
