A carbon material has at least either a peak related to diamond bonds, or a peak related to diamond-like bonds, appearing in a range of 1250 to 1400 cm−1 in a spectrum measured by Raman scattering spectrometry, and a full width at half maximum of a maximum peak, or each of full widths at half maximum of the maximum peak and a second largest peak, among peaks appearing in the range of 1250 to 1400 cm−1, has a signal less than 100 cm−1.
