Suction filter and fuel supply device

A suction filter that filters a fuel in a fuel tank of a vehicle and then allows the fuel to be drawn into an intake port of a fuel pump, the suction filter comprising:

• a filter element disposed in the fuel tank and formed of a filter sheet with a hollow shape to define an inner space therein, the filter element filtering a stored fuel that is the fuel stored in the fuel tank when the stored fuel passes through the filter sheet into the inner space;
• a dividing wall element disposed to divide the inner space into a first space, into which a filtered fuel that is the fuel filtered by the filter element flows, and a second space, to which the intake port drawing in the filtered fuel is opened, and enclosing the first space together with the filter element and enclosing the second space together with the filter element;
• and
• a first passage element including a first inflow port opened to the first space at a position in an upper half in the first space and a first outflow port to which an intake pressure is applied by the intake port, and defining a flow passage through which the filtered fuel flows from the first inflow port toward the first outflow port;
• and
• a second passage element including a second inflow port opened to the second space and a second outflow port to which the intake pressure is applied by the intake port, and defining a flow passage through which the filtered fuel flows from the second inflow port toward the second outflow port.
