To provide a protrusion structure control device that can control a peripheral air flow only in an objective speed range while suppressing increase in frictional resistance against an air flow and noise in other speed ranges.SOLUTION: A protrusion structure control device 100 includes: a substrate 101 provided with a first region 102 and a second region 103 respectively having different contact angles, on at least one surface 101a; and temperature control means 106 for controlling temperatures of the first region 102 and the second region 103. The first region 102 is installed in a position of forming a protrusion structure, while the second region 103 has a contact angle that is larger than the first region 102 and is installed in a periphery of the first region 102.SELECTED DRAWING: Figure 1
