PROBLEM TO BE SOLVED: To provide a mist supplying apparatus for supplying a mixture of oil mist, which is very small particulate mist, in an extremely low concentration with air by a relatively simple means. SOLUTION: High pressure air at a small flow rate is supplied to the inside of a first venturi tube 3 to lower the pressure of an aperture part of an oil conveyance pipe 4, and oil 6 is led into the inside of the first venturi tube 3 and pulverized and finely granulated by the air current to spray the resulting primary mist into a mist tank 5. While the primary mist generates convection current in the mist tank 5, oil particles with a large particle size are precipitated and removed to obtain secondary mist. High pressure air at a high flow rate is supplied to the inside of a second venturi tube 9 to lower the pressure of an aperture part of a secondary mist leading-pipe and the secondary mist is led into the inside of the second venturi tube 9 and floats along with air current to produce oil mist at an extremely low concentration or a mixture with air and the oil mist or the air mixture is discharged.
