Abstract
An object of the present invention is to provide a production method for composite resin particles containing a fluororesin and a carbon nanomaterial and having excellent moldability while maintaining conductivity, the present invention provides a production method for composite resin particles containing a fluororesin and a carbon nanomaterial, comprising: a step of separating the fluororesin in the presence of a dispersion medium; a step of obtaining a dispersion containing the fluororesin, the carbon nanomaterial, and the dispersion medium by dispersing the fluororesin and the carbon nanomaterial in the dispersion medium; and a step of removing the dispersion medium by storing the dispersion in a drying container having a bottom surface, and drying the dispersion under conditions in which a dry area calculated by the following equation (1) is in a range of 20˜100 [cm2/g], Dry area=(S/W1) . . . (1), wherein S is an area [cm2] of the bottom surface of the drying container, and W1 is a mass [g] of the composite resin particles in the dispersion.
