Abstract: Provided is a fuel cartridge in which a follower is prevented from being deformed and from separating even when heavy vibration is exerted onto the fuel cartridge. The fuel cartridge is detachably connected with a fuel cell main body and assumes a construction in which the fuel cartridge is equipped with a fuel-storing vessel for storing a liquid fuel, a fuel discharge part, and a follower which seals the liquid fuel and moves as the liquid fuel is consumed at a rear end part of the liquid fuel. The follower is provided with a follower auxiliary member and a cap member both of which have no fluidity and are insoluble in the liquid fuel.
