A novel micro / nano bubble generation method, a micro / nano bubble generation system, and a microreactor having the micro / nano bubble generation system are provided. Moreover, the cleaning method of the microchannel excellent in the washability and / or bactericidal property is provided. A step of introducing a liquid into a microchannel and a pressurized gas from the outside of a porous wall having through holes with a radius of 10 to 1,000 nm formed in all or part of the microchannel wall A method of generating micro-nano bubbles, comprising a step of supplying micro liquid bubbles into the liquid by supplying gas into the micro flow path by a supply means.
