PROBLEM TO BE SOLVED: To provide a lattice-like sheet material having a novel function, and a blind and a bag each using the lattice-like sheet material.SOLUTION: In the lattice-like sheet material, a standing condition where lattices are formed by intersecting, in a standing state, a plurality of vertical bands 10 which are extended in a first direction X and are provided with slits at prescribed intervals, and a plurality of transverse bands 20 which are extended in a second direction Y intersecting with the first direction X and are provided with slits at prescribed intervals, is regarded as an initial condition. The vertical bands 10 and the transverse bands 20 are structured to be latched together via the slits formed at the intersecting parts of both of the band parts and to be alternately exchanged in the directions of the slits extending from the edge sides of the vertical bands 10 and the transverse bands 20 in every intersecting part. The intersecting angle between the vertical bands 10 and the transverse bands 20 at the intersecting parts is varied in accordance with an applied external force so as to be changed into the condition where the vertical bands 10 and the transverse bands 20 fall down, from the standing condition. |
