An electrode for secondary batteries, in which an alkali metal of an active material is carried by a carrier, whose principal component is the carbonaceous material of the multilayer structure comprising a surface layer and the nucleous enveloped therein and satisfies the following conditions: (1) a true density ρ is not less than 1.80 g/cm³; (2) in Raman spectroscopic analysis using the argon ion laser beam of 5145 Å in its wavelength, peaks P A and P B exist within the ranges of 1580-1620 cm⁻¹ and 1350-1370 cm⁻¹ respectively, and the ratio R = I B /I A of the intensity I B of P B to the intensity I A of P A is not less than 0.4. |
