According to the present invention, a rotor blade having a surface fine pattern comprises: a rotor blade main body provided in an unmanned aerial vehicle and rotating around a coupling unit to generate a driving force required for flight of the unmanned aerial vehicle; and a pattern unit formed on a surface of the rotor blade main body to reduce noise generated as the rotor blade main body rotates. The pattern unit can be formed in a gradation structure in which a diameter decreases toward an edge of the rotor blade main body to correspond to an airfoil shape of the rotor blade main body. The pattern unit is formed in a pattern structure repeated by being spaced apart from each other with respect to a longitudinal direction and a width direction of the rotor blade main body to disperse a flow of a vortex generated around the rotor blade main body to reduce noise caused by the rotation of the rotor blade main body.
