摘要：
An air filter sheet comprising particles of a functional agent with an average particle diameter of 0.1 to 30 μm and fibrils of a polytetrafluoroethylene resin with a number average molecular weight of 3,000,000 to 50,000,000, the ratio by weight of the functional agent to the fibrils of the polytetrafluoroethylene resin being from 1 to 99. According to the present invention, an air filter sheet comprising fibrils of polytetrafluoroethylene resin with a functional agent carried thereon, possessing excellent formability, and being free from a lubricant, a process for manufacturing the air filter sheet, and an air filter free from contamination of outgas with a lubricant are provided.
