Abstract
By using CNF excellent in dispersibility, conductivity, and crystallinity, a conductive polymer material having high conductivity even with a low CNF content and a shaped article thereof and a conductive polymer material with a less CNF content for same conductivity and a shaped article thereof are provided. A conductive polymer material with high conductivity is produced by using carbon nanofiber with a median diameter D50 value from 0.1 to 8 μm, powder resistivity of 0.03 Ωcm or less measured under a load of 9.8 MPa, and D/G from 0.5 to 1.3.
