Ferroelectric liquid crystals are of considerable theoretical and technological interest. It has so far been recognized that a tilted smectic phase made up of chiral molecules can be ferroelectric. However considering that the most essential thing is to attach the polar symmmetry to systems, we can say that ferroelectric liquid crystal do not necessarily to be chiral. We descrive a distinct ferroelectric smectic liquid crystal which is formed from the aciral molecules with the banana shape. The origin of the ferroelectricity is ascribed to the C_2v polar symmetry which is produced by the efficient packing of the banan shaped molecules into a smectic layer. This is the first obvious example of ferroelectricity in achiral smectic phase which is ascribed to the C_2v symmetry of the molecular packing into a layer.
