We have performed the valence‐band photoemission spectroscopy on single‐wall carbon nanotubes. Characteristic peak structures originated from one‐dimensional van Hove singularities have been successfully observed. The peak structures are well reproduced by the calculation based on the tight‐binding model taking into account a diameter distribution of nanotubes.
