The possibility of superconducting and insulating instability is examined in the one‐dimensional electron system with Coulomb interparticle interaction that is evaluated in the plasmon‐pole approximation. The insulating instability appears to dominate strongly over possible superconductive effects. The dependence of its mean‐field transition temperature on the band width is presented in graphic form for various degrees of band filling and the free‐particle energy spectrum as well as the tight‐binding energy spectrum is considered.
