Abstract: A nonwoven fabric includes a fiber including a first portion and a second portion connected to the first portion. A first fiber diameter of the first portion is smaller than a reference fiber diameter. A second fiber diameter of the second portion is equal to or greater than the reference fiber diameter. The reference fiber diameter is smaller than 1 μm. A ratio of a maximum fiber diameter of the second portion to a length of a linear line connecting both end portions of the second portion is from 1/10 to ⅓.

Abstract: A non-woven fabric includes nanofibers which contain a polymer and inorganic particles, the nanofibers being formed by an electrospinning method. The inorganic particles contain first particles and second particles, some parts of which are exposed from a surface of the polymer. A volume V1o of a portion of the first particles exposed from the surface of the polymer and a volume V1i of a portion buried in the polymer satisfy a relationship of V1o N2.

Abstract: A laminated nonwoven fabric includes first to third nonwoven fabrics and an adhesive sandwiched between at least the second nonwoven fabric and the third nonwoven fabric. The second nonwoven fabric contains second fibers and is laminated on the first nonwoven fabric containing first fibers, and the third nonwoven fabric contains third fibers and is laminated on the second nonwoven fabric on an opposite side to the first nonwoven fabric. An average fiber diameter of the first fibers is larger than that of the second fibers. The second nonwoven fabric has first and second regions which exist mixedly with each other, and a density of the second fibers in the second region is lower than that in the first region. A part of the adhesive is present between a portion of the first nonwoven and a portion of the third nonwoven fabric which face the second region.

The separator includes a plurality of nanofibers and has a form of a sheet having a first surface and a second surface opposite thereto. When the average maximum fiber diameter of the nanofibers in the plane direction of the separator is compared between in vicinities of the first and second surfaces and at a center portion in the thickness direction of the separator, average maximum fiber diameters Ds1 and Ds2 of the nanofibers in the vicinity of the first and second surfaces are smaller than an average maximum fiber diameter Dc of the nanofibers at the center portion in the thickness direction of the separator.
