Abstract

The invention provides a component that exhibits steam resistance and acid resistance, that is less likely to swell and contract with an alkali, and that is less likely to cause dissolution of filler. The component includes a surface that is to be in contact with a solution having a pH of 8.0 or higher. This surface contains a crosslinked product of a fluorine-containing amorphous elastomer that is a copolymer containing: vinylidene fluoride; a fluorine-containing monomer represented by the following formula (1): CH<2>=CFRf, wherein Rf is a C1-C12 fluoroalkyl group which is linear or branched and in which any or all of the hydrogen atoms are replaced by fluorine atoms; and a third monomer copolymerizable with these monomers. The elastomer contains a unit of the vinylidene fluoride and a unit of the fluorine-containing monomer represented by the formula (1) in a mole ratio of 87/13 to 20/80. The elastomer contains a unit of the third monomer in an amount of 0 to 50 mol% of all the monomer units. The elastomer has a glass transition temperature of 25°C or lower.
