PROBLEM TO BE SOLVED: To provide a non-woven fabric sheet having a low pressure loss and a high collection performance, and a filtering material by using the same. SOLUTION: This melt-blown non-woven fabric is characterized by containing mainly of a non-electroconductive fiber, and consisting of 10-30% ratio of the fiber having 0.1-1.5μm fiber diameter, and 30-60% ratio of the fiber having 3-10μm fiber diameter. The filtering material by using the melt-blown non-woven fabric is also provided. COPYRIGHT: (C)2006,JPO&NCIPI
