Abstract
Provided is a method of producing a composite resin material that has excellent shapeability and enables supply of a shaped product having good properties. The method of producing a composite resin material includes: a mixing step of mixing a fluororesin, fibrous carbon nanostructures, and a dispersion medium to obtain a slurry; and a formation step of removing the dispersion medium from the slurry and forming a particulate composite resin material. The particulate composite resin material has a D50 diameter of at least 20 μm and not more than 500 μm and a D90 diameter/D10 diameter value of at least 1.2 and not more than 15. The D10 diameter, D50 diameter, and D90 diameter are particle diameters respectively corresponding to cumulative volumes of 10%, 50%, and 90% calculated from a small particle end of a particle diameter distribution of the particulate composite resin material.
