The invention provides a temporary fixing sheet comprising a polysiloxane foam layer having excellent antistatic performance and good appearance. In one embodiment of the present invention, the temporary fixing sheet is a polysiloxane foam layer, which is composed of an organopolysiloxane containing (A) at least two alkenyl groups in a molecule, (B) an organic polysiloxane having at least two silicon atoms bonded to hydrogen atoms in one molecule, (C) a mixture containing water and an inorganic thickener, (D-1) a non-HLB value of 3 or more Ionic surfactants: 0.2 to 1.2 parts by mass with respect to 1 part by mass of (G) component, nonionic surfactants having a value of (D-2) HLB less than 3: 1 to (G) component The mass part is 0.01 to 0.14 mass part, and it is formed by the polysiloxane resin composition of (E) a hydrosilylation reaction catalyst, (F) a hardening retarder, and (G) a conductive substance. |
