PROBLEM TO BE SOLVED: To provide a low-cost aspiration mask providing high air permeability rate and effective capturing ability of fine solid particles such as pollens, and a filter body for an indoor cleaner. SOLUTION: The filter body is a filter medium comprising an outer layer or an inner layer and a core layer, or an outer layer, an inner layer and a core layer. In the filter body, the core layer is impregnated with viscous liquid, thereby effectively adsorbing and removing fine particles which are passed through a dried hole surface without being captured, while maintaining high air permeability.
