PROBLEM TO BE SOLVED: To provide a small-sized gas and liquid rough mixer for spray to which a flexible thin tube can be connected, a satisfactory spraying state can be easily obtained and the amount of spraying can be controlled. SOLUTION: The gas and liquid rough mixer for spray which can be operated by increasing pressure if necessary has a liquid tank B to which a gas feeding pressure tube A is inserted and a constant pressure can be applied and maintained. One liquid outflow thin tube C is inserted to the lower part of a liquid phase part in the liquid tank B, another gas outflow thin tube D is connected to a gas phase part in the upper part of B or to A, and the other ends of the tubes C and D are connected at the lower part of B to provide a single gas and liquid mixing thin tube E.
