Abstract
Disclosed is a composite resin material which includes a fluororesin and fibrous carbon nanostructures, wherein the composite resin material has a fluororesin content of 70% by mass or more and a fibrous carbon nanostructure content of 0.01% to 0.5% by mass based on the amount of the fluororesin, and wherein when a 50 μm thick shaped product obtained by shaping the composite resin material is observed with an optical microscope, the number of aggregates that contain the fibrous carbon nanostructures as a main component and have a diameter of 300 μm or more is 3 or less in a 30 mm×30 mm field of view.
