PROBLEM TO BE SOLVED: To provide a membrane material, excellent in heat shield performance particularly to solar radiation, excellent in natural lighting performance, capable of coloring, and capable of sewing by a high frequency welder. ! SOLUTION: A flexible sheet has a near-infrared shielding layer of at least one layer, and the near-infrared shielding layer includes a thermoplastic resin, a conductive metal oxide particulate of an average primary particle diameter of 0.01-0.20 μm and a barium sulfate particle of an average particle diameter of 0.3-1.2 μm, and the near-infrared shielding layer includes 3-20 mass% by putting the conductive metal oxide particulate and the barium sulfate particle together, and in the near-infrared shielding layer, the mass ratio of the conductive metal oxide particulate and the barium sulfate particle is set to 1: 2-1: 10. !
