A flying body, which prevents others from measuring precise position of the flying body and allows friends to measure precise position of the flying body, is provided. The flying body (10) is provided with a reflector (100), a controller (300) and an anti-reflection section (200). The reflector (100) is provided with a reflective surface, arranged in an aperture, which reflects a radiated laser. The controller (300) generates a control signal on a basis of a state of the flying body. The anti-reflection section (200) prevents a reflection of the laser by the reflective surface on a basis of the control signal.
