The ultimate tensile strength of individual single‐walled carbon nanotubes (CNTs) is measured in a high‐resolution TEM equipped with a conducting AFM unit. The values are correlated to every tube’s structural details. The strength of ∼100 GPa, approaching the theoretical limit for defect‐free CNTs, is documented in tubes without visible defects; for those with spatially separated stepwise pentagon‐heptagon defects, determining the breaking sites, it reduces to 40–70 GPa.
