PURPOSE: A nano bubble generator is provided to generate nano bubbles in middle operation, in latter operation, and even in early operation, thereby stably nano bubbles in short time. CONSTITUTION: A nano bubble generator comprises a plurality of mixing pump(10,20). The mixing pump mixes and pressurizes liquid and air, and shears gas, thereby generating nano bubbles. The mixing pumps are arranged in a line in order to more miniaturizing micro bubble gradually. The plurality of mixing pump comprises a first mixing pump(10) and a second mixing pump(20). The first mixing pump receives fluid and gas, and generates micro bubbles. The second mixing pump receives air and liquid-mixed flow in which micro bubbles are generated by the first mixing pump. The second mixing pump more miniaturized the micro bubbles.
