Abstract: A battery includes a positive electrode, a negative electrode, a separator interposed therebetween, and an electrolyte. 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.

Abstract: A laminated nonwoven fabric includes a first nonwoven fabric that comprises first fibers, and a second nonwoven fabric that comprises second fibers. The second nonwoven fabric is laminated on the first nonwoven fabric. An average fiber diameter D1 of the first fibers and an average fiber diameter D2 of the second fibers satisfy a relation of D1>D2. In viewed from a side of a principal surface of the second nonwoven fabric being not opposed to the first nonwoven fabric, a total area of first portions of the second fibers superimposed on the first fibers and existing on the nearer side than the first fibers is larger than a total area of second portions of the second fibers existing and superimposed on voids S of the first nonwoven fabric formed of the first fibers.

Abstract: A laminate includes a first sheet containing first fibers, a second sheet laminated on the first sheet and containing second fibers, and an adhesive disposed between the first sheet and the second sheet. At least a part of the adhesive is disposed in an end portion along the edge side of the laminate so as to form a linear first region, and the first sheet is adhered to the second sheet via the first region. Alternatively, a mass per unit area of the adhesive present in an end portion along an edge side of the laminate is larger than a mass per unit area of the adhesive present in a portion near a central part of the laminate rather than the end portion.

Abstract: A laminated nonwoven fabric includes a first nonwoven fabric containing first fibers, a second nonwoven fabric laminated on the first nonwoven fabric and containing second fibers, a third nonwoven fabric laminated on the second nonwoven fabric on an opposite side to the first nonwoven fabric and containing third fibers, and an adhesive containing a plurality of particles. Some of the plurality of particles of the adhesive is attached to the second nonwoven fabric. At least one of the first nonwoven fabric and the third nonwoven fabric is adhered to the second nonwoven fabric via the some of the plurality of particles of the adhesive. An average fiber diameter of the first fibers is larger than the average fiber diameter of the second fibers, and an average particle diameter of the plurality of particles of the adhesive is smaller than the average fiber diameter of the first fibers.
