A temporary fixing material has a temporary fixing performance such that it can be used for temporarily fixing precision electronic parts made of glass, metals, etc. with ease, and which also can be easily removed from the adherend; an ability to remove contaminants before the temporary fixing; and an antistatic performance such that it can remove static electricity occurring at the time of removal thereof. The temporary fixing material includes a base substrate and a polymer gel, usable for temporarily fixing electronic parts during conveyance or processing thereof, a specific polymer gel is utilized which comprises: a polymer matrix obtained by copolymerization-crosslinking of a polymerizable monomer having in its molecule at least one polymerizable carbon-carbon double bond and a crosslinkable monomer having in its molecule at least two polymerizable carbon-carbon double bonds; and water having dissolved therein at least polyvinyl alcohol-type polymer, the water being retained in the polymer matrix. |
