<P>PROBLEM TO BE SOLVED: To provide a coolant supplying device capable of being miniaturized. Ž<P>SOLUTION: This coolant supplying device 1 supplies coolant to a machining machine 2. A stock liquid metering tank 5, a diluting machine 8, an intermediate adjusting tank 10 and a pump 12 are arranged on a lower side of a stock liquid tank 4. A joint part of a stock liquid supply pipe 6 and the stock liquid metering tank 5 is constituted of a pipe inserting hole 14 formed in the stock liquid metering tank 5 and inserted with the stock liquid supply pipe 6 and a flexible insertion part 15 with flexibility formed at a portion inserted into the pipe inserting hole 14 of the stock liquid supply pipe 6. Each of a stock liquid metering sensor 7 and a diluted solution metering sensor 11 is provided on a side part of each of the tanks 5 and 10. Coolant stock liquid and water pressure in relation to the diluting machine 8 are made to have a fixed pressure by the stock liquid metering tank 5 and a regulator 18 to stabilize a dilution ratio.
