It is shown that charge ordering in layered crystalline metals causes an\nincrease in the normal state energy of the conducting layers. If this increase\nin the energy exceeds the difference between the superconducting state energy\nand the normal state energy of the metal, then the superconducting transition\noccurs. A relation between the charge gap in the superconducting phase and the\nbandgap width in the undoped insulating phase of high-temperature\nsuperconductors is obtained.\n
