Claim Text:
1. Aggregates comprising composite carbon fibers, in which the composite carbon fibers comprise multiwalled carbon nanotubes having a fiber diameter of from 5 nm to 30 nm and an aspect ratio of from 100 to 1000 and graphitized carbon nanofibers having a fiber diameter of from 50 nm to 300 nm, wherein the multiwalled carbon nanotubes are homogeneously dispersed between the graphitized carbon nanofibers and near the surface of the graphitized carbon nanofibers, and the dispersion state is a state where carbon nanofibers extend through the space between carbon nanotubes disentangled in a loose state.
