The present invention relates to a method for attaching a micro bubble array on a plate surface, and more particularly, to a method for attaching micro-sized bubbles on a plate surface so as to reduce fluid frictional resistance caused by flow on the plate surface that encounters with liquid. The method for attaching a micro bubble array on a plate surface according to one aspect of the present invention includes a micro groove forming step and a hydrophobic treatment step. In the micro groove forming step, a plurality of grooves with a size of 1 to 1,000 micrometers are formed in a plate surface to be arranged therein. In the hydrophobic treatment step, the plate surface having the grooves formed therein is coated with a material having a hydrophobic property. Since the plate surface has the plurality of grooves arranged therein and also is treated with a hydrophobic material, micro bubbles are formed on the micro grooves when the plate surface goes under water. According to the present invention, the fluid frictional resistance may be reduced using slide occurring between air bubbles and liquid by forming micro bubbles on a plate surface.
