[Problem] To provide a parachute having a float that can exhibit greater long-term buoyancy than is conventional, without being damaged during deployment, and a safety device and a flying body comprising the same. [Solution] A parachute 10 comprises: an umbrella body 40 that becomes substantially hemispherical during deployment; and a dual-structure float member 52 having an outer bag-like member 60 formed by a fabric-like body, and an inner bag-like member 70 provided inside the outer bag-like member 60 and formed by a film-like body. The parachute is characterized in that: a ventilation port 42 that opens during deployment is formed in the umbrella top portion of the umbrella body 40, and the float member 52 is provided on the outside of the ventilation port 42; the inner bag-like member 70 has an intake port 71 connected to the ventilation port 42; and during deployment of the umbrella body 40, air flows into the umbrella body through the ventilation port 42 and the intake port 71, thereby expanding the umbrella body together with expanding the outer bag-like member 60.
