A method for manufacturing an ultra-thin elastomer sheet comprising:

preparing a silicone polymer configured from a plurality of unit portions having reactive organic groups and a plurality of unit portions not having reactive organic groups, and a crosslinking agent having units including reaction groups that reacts the reactive organic groups so that a number of unit portions that do not react the reaction groups of the crosslinking agent among the silicone polymer which defined by the following mathematical formula (II)
[mathematical expression 1]
U′=(U′m+U′n)/U′a (II)
wherein, in mathematical formula (II), U′ is a number of monomer unit portions that do not react reaction groups of the crosslinking agent in silicone polymer, U′m is a number of monomer unit portions that do not have reactive organic groups of silicone polymer, U′n is a number of monomer unit portions that have reactive organic groups of silicone polymer, and U′a is a number of reaction groups of the crosslinking agent,
is 348-2090,
then, producing a crosslinked silicone polymer through dissolving the silicone polymer and the crosslinking agent in a solvent, subsequently adding a catalyst and reacting the reactive organic groups and the reaction groups of the crosslinking agent, and
film-producing a thin film sheet having a maximum film thickness of 3 μm from the crosslinked silicone polymer.
