PROBLEM TO BE SOLVED: To provide a blowby gas filter capable of precluding drop of the thermal efficiency of an internal-combustion engine by suppressing a pressure loss in the process of filtrating the particulate substance or oil mist of nm-order contained in the blowby gas generated in the engine. SOLUTION: The filter to purify the blowby gas of the internal-combustion engine is composed of a housing and hollow yarn film bundles filling the housing while they are arranged approximately parallel with the blowby gas flowing direction.
