Abstract: A filter device has a sub-tank to be provided in a fuel tank. The sub-tank has an outer tubular portion and a bottom wall. A communication hole is formed in the bottom wall. An upper-side filter element is fixed to an upper side of the bottom wall to form an upper-side filter space between them, while a lower-side filter element is fixed to a lower side of the bottom wall to form a lower-side filter space between them. An inlet port of a fuel pump is connected to the upper-side filter element. Apart of fuel can be reserved in a fuel holding portion of the inside of the sub-tank and/or in the upper-side filter space, even when fuel amount in the fuel tank is decreased and the fuel tank is inclined with respect to a horizontal line.
