Abstract We have studied the behavior of two holes in the CuO₂ plane of cuprate superconductors which is important for making clear the origin of the superconductivity. The interaction between two holes does not show a simple form but a damped oscillating function of the distance between them. It is favorable for them to get closer with a distance about five or ten lattice constant just by thermal motion. Around the equilibrium positions, the vibration motion is considered.
