Abstract: There is provided a filter which includes a fiber layer and an adsorbent. The fiber layer includes fiber. The adsorbent is held in the fiber and adsorbs a chemical substance. The filter is divided into a plurality of sections by a fold. Each of the plurality of sections includes a first end portion positioned along the fold, a center portion adjacent to the first end portion, and a second end portion which counterposes the first end portion with the center portion interposed. The density of the adsorbent at the center portion is greater than the density of the adsorbent at the first end portion and at the second end portion.

Abstract: There is provided a stacked body which includes a porous base layer, a porous charged layer, a very fine-fiber layer, and an adsorbent. The base layer is configured with base fiber. The charged layer is configured with charged fiber. The very fine-fiber layer is interposed between the base layer and the charged layer and includes very fine fiber. The adsorbent is held in the very fine fiber and adsorbs a chemical substance. An average fiber diameter of the charged fiber is greater than an average fiber diameter of the very fine fiber.

Abstract: A laminated nonwoven fabric includes a first nonwoven fabric containing first fibers, a second nonwoven fabric containing second fibers, a third nonwoven fabric containing third fibers, and an adhesive. The second nonwoven fabric is laminated on the first nonwoven fabric, and the third nonwoven fabric is laminated on the second nonwoven fabric on an opposite side with respect to the first nonwoven fabric. The adhesive is disposed between the first nonwoven fabric and the third nonwoven fabric. An average fiber diameter of the second fibers is equal to or less than 3 μm, and is smaller than an average fiber diameter of the first fibers. The third nonwoven fabric has a protrusion including a part of the third fibers entangled with each other on a surface facing the second nonwoven fabric. At least a part of the adhesive is disposed between the protrusion and the first nonwoven fabric.
