An oil pan for attachment to the lower wall of the engine block housing of an internal combustion engine by bolts in such a way that lubricating oil is stored in the oil pan and transported from the oil pan to various parts of the engine to be lubricated by a suction line connected to an oil pump, in which excess oil flows back directly into the oil pan. The oil pan has a pan body (1) which is formed of a synthetic material and is closed along its upper portion by a connecting plate (2), also formed of a synthetic material, in which each of the two surfaces of the connecting plate is provided with a circumferential seal (8,9) that is cast onto the plate to ensure a tight seal between the pan body (1) and the engine block. The bottom portion of the connecting plate (2) extends as a tubular connecting piece (5), which is provided at its free end with a filter screen (6), and which forms a segment of the suction line.
