• The Marangoni instability of a thin liquid sheet driven by the surface tension gra-dient (due to variations of temperature or of mass concentration) is studied by meansof a linear theory. It is found that the critical Marangoni number for the steady modecan be expressed by a simple function of the wave-number when the two boundariesof the sheet are flat. When the surface deformations are taken into account, anothertype of instability may occur for small values of the Biot number. The effect of devia-lion of the surface tension coefficient from the mean value at the free surfaces and theresulting surface patterns made up by the surface deformations at small wave-numbers are also discussed.
