Abstract
A modified fluororesin material containing a modified fluororesin which contains a tetrafluoroethylene unit, a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene, and a tertiary carbon atom. The tertiary carbon atom is present in an amount of 0.001 to 0.030 mol % of a total amount of the tetrafluoroethylene unit and the modifying monomer unit. The modified fluororesin material has a linear expansion coefficient at 20° C. to 200° C. that is 10% or more lower than that of a non-modified fluororesin material. The non-modified fluororesin material contains a tetrafluoroethylene unit and a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene and containing no tertiary carbon atom. Also disclosed is a material for a circuit board including the modified fluororesin material, a laminate for a circuit board, a circuit board, and a method for producing the modified fluororesin material.
