<p>Provided is a separation membrane coating device capable of preventing a change in composition of a coating solution when coating a separation membrane for a secondary battery with inorganic particles having heat resistance, by minimizing volatilization of a solvent. The separation membrane coating device may comprise: supply chambers (12, 13) which are formed within a main body (10) and accommodate the coating solution; a coating bar (15) installed so as to be able to transfer the coating solution to a separation membrane (1) being transferred; and recovery chambers (24, 25) for recovering the remaining coating solution after coating the separation membrane (1). The coating bar (15) can spin in the same direction as the transfer direction of the separation membrane (1).</p> |
