Abstract
An inorganic fiber sizing agent that contains at least one carbon nanostructure selected from the group consisting of carbon nanotubes and carbon nanofibers, a resin, and a surfactant. If the total content of a nonvolatile content of the resin and the surfactant is taken as 100 parts by mass, the inorganic fiber sizing agent contains the surfactant at a ratio of 2 to 50 parts by mass.
