    Abstract: A fiber assembly includes, on a main surface of a support sheet subjected to a release treatment, a warp yarn group in which a plurality of warp yarns including a polymer material are arranged, and a weft yarn group in which a plurality of weft yarns including a polymer material are arranged. The warp yarn group and the weft yarn group form a plurality of first contact portion regions and a plurality of non-contact portion regions. Each of the plurality of first contact portion regions is a region in which at least one of the plurality of warp yarns is integrated with at least one of the plurality of weft yarns. Each of the plurality of warp yarns has a line width of 1 μm to 10 μm, inclusive, and each of the plurality of weft yarns has a line width of 1 μm to 10 μm, inclusive. At least one of the plurality of first contact portion regions has a fiber density higher than that of at least one of the plurality of non-contact portion regions. Two of the plurality of warp yarns or two of the plurality of weft yarns have a spacing of 5 μm or more and 1000 μm or less in at least one of the plurality of first contact portion regions. Two of the plurality of warp yarns or two of the plurality of weft yarns have a spacing of 2000 μm or more in at least one of the plurality of non-contact portion regions.

    Abstract: A fiber mesh sheet is provided, in which the fiber mesh sheet has a mesh structure in which two or more layers of planar fiber arrangement groups are laminated, where, in each of the planar fiber arrangement groups, longitudinal directions of a plurality of fibers made of a polymer material are arranged in a plane along one direction, longitudinal directions of the fibers in one of the fiber arrangement groups intersect those of the fibers in the other fiber arrangement group in two adjacent layers of the fiber arrangement groups at an intersecting angle of 30° or more and 150° or less in a plan view seen from a direction perpendicular to the plane, an upper part of a cross section of the fiber in the fiber arrangement group at a lowermost layer is a substantially circular shape, and a lower part of a cross section of the fiber in the fiber arrangement group at the lowermost layer is a substantially flat shape, where the upper part is a side on which the adjacent fiber arrangement group is present, and the lower part is a side on which the adjacent fiber arrangement group is not present, and a cross section of the fiber in the fiber arrangement group at a layer other than the lowermost layer is a substantially circular shape.

    Abstract: A magnetostrictive element that can exhibit a sufficiently large magnetostriction amount in a longitudinal direction is formed of a single crystal alloy magnetostrictive material. The magnetostrictive element has a shape of a plate-shaped rectangular parallelepiped, a main plane of the plate-shaped rectangular parallelepiped includes a plurality of magnetic domains that are regions where atomic magnetic moments are arranged in the same direction and whose width is 10 μm to 200 μm, and a total area rate of a magnetic domain where an angle difference between a lateral direction of the main plane and a direction of the magnetic moments of the magnetic domain is 10° or less to the main plane is 60% to 100%.
