Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a slat, the mass of which can bee lowered while maintaining rigidity than when a plurality of reinforcing plate parts (ribs) are integrally formed, a shutter curtain, and an opening and closing device.SOLUTION: When a bending force acts on a slat body as in the case where a tensile force is imparted to a region of a wall part in which a wire is arranged, the tensile force generated in the wall part is transmitted to the wire via an attachment member. Thereby, deformation of the slat body is suppressed. Thus, even when the slat body has no reinforcing plate part (rib), rigidity of the slat body is maintained.SELECTED DRAWING: Figure 1 【課題】複数の補強用の板部（リブ）が一体的に形成されている場合と比して、剛性を維持した上で、スラットの質量を軽くすることができるスラット、シャッターカーテン、及び開閉装置を得る。【解決手段】線材が配置されている壁部の部位に張力が付与されるような、曲げ力がスラット本体に作用すると、取付部材を介して、壁部に生じた張力が線材に伝達される。これにより、スラット本体の変形が抑制される。このように、スラット本体に補強用の板部（リブ）が無い場合であっても、スラット本体の剛性が維持される。【選択図】図１
