A tobacco filter stock capable of being molded into a filter only be entanglement of filaments with one another without any adhesion means, whereby the resulting filter has a suitable hardness and a superior whiteness. A tobacco filter and a production process thereof are provided, whereby the tobacco filter stock comprises a ton of crystalline polyolefin filaments, preferably crystalline polypropylene filaments, having a single filament denier of 1 to 6 d/f, a total denier of 30,000 to 60,000 D 40 to 60 crimps/25 mm filament, a crimp elastic modulus of 2.5 to 5.0, a frictional coefficient between filaments of 0.20 to 0.37 and a height ratio (height/width) of 0.01 to 0.1.
