To provide a fuel container preventing fuel from leaking outside when storing the fuel in the fuel container or supplying it to an apparatus main body therefrom.

The fuel container 1 for supplying the fuel to the apparatus main body has a fuel storing part 2 storing fluid fuel and a connection part 3 detachably connected to the apparatus main body mounted on the fuel storing part 2. The connection part 3 has a switching valve 5 and a fracture seal member 4. The switching valve 5 is constituted so as to open when the fuel storing part is connected to the apparatus main body and close when the fuel storing part is separated from the apparatus main body. The fracture seal member 4 made of a material hardly corroded by the fluid fuel is constituted so as to seal the fluid fuel in the fuel storing part 2 arranged between the switching valve 5 and the fuel storing part 2, and to be broken when the fuel container 1 is connected to the apparatus main body for the first time, and to release the fluid fuel in the fuel storing part 2.
