Abstract: The present invention addresses the problem of providing: an electret nonwoven fabric that has high collection efficiency, low pressure loss, and high strength as a result of using fine fibers and by controlling the fusing between the fibers; and an air-filter filtering material using the same. This nonwoven fabric is characterized in that: the fibers constituting the fabric are made of a thermoplastic resin; the fibers include at least a first component and a second component; the first component and/or the second component contains a crystal nucleating agent; the difference in the crystallization start temperature between the first component and the second component is 5°C or greater; and at least a portion of the first component and the second component is exposed on the surface of the fibers.
